My Sister Planned a Lie Detector Contest for My Fiancé and Me at My Wedding—the Wedding Was Canceled After Taking It

I always thought my wedding day would be unforgettable for all the right reasons. Instead, it became unforgettable for a reason I could never have imagined. It all began when my sister brought a lie detector test to the wedding.

I’m Harlene, a 28-year-old teacher, and until recently, I thought I had the perfect life. My fiancé, Mark, and I had been together for five wonderful years, planning a future filled with love and laughter. That future vanished the moment my sister, Melissa, turned my wedding into a nightmare.

Let me explain.

Mark and I met through a mutual friend five years ago, and from the moment we connected, it felt like we’d known each other forever.

He was very kind and sensitive to everyone’s feelings around him. What I loved the most about him was how he respected everyone equally and never shied away from helping others.

It didn’t take time before we became inseparable. We’d spend weekends exploring new restaurants, binge-watching sitcoms, and dreaming about the future.

“Har,” he’d say with a teasing grin, “if you weren’t such a good cook, I’d probably starve to death.”

“Good thing I love feeding you,” I’d reply, laughing as he polished off yet another plate of lasagna.

Mark worked as a software developer, a job that sometimes kept him at his desk late into the night. I never minded, though. I understood his dedication and appreciated the effort he put into his career.

As for me, I was living my dream as a teacher. My students were my little rays of sunshine, and I loved every chaotic, beautiful moment of my job.

When we decided to get married, we both agreed that our wedding should be a celebration of love and fun. We wanted everyone to feel as happy as we did.

“Let’s make it the kind of wedding people will talk about for years,” Mark said one evening as we brainstormed ideas.

“Definitely,” I replied. “How about games? Fun ones that get everyone involved?”

“Perfect,” he said, his eyes lighting up. “We can have trivia or charades or something. Maybe even a karaoke battle.”

We even looped in my sister, Melissa, for some ideas. At the time, she didn’t seem particularly interested.

“I don’t know,” she said with a shrug. “You guys are the creative ones. Just tell me what to do, and I’ll help.”

With Melissa’s lackluster input, Mark and I continued planning the wedding of our dreams. Every detail mattered to us, from the playlist to the seating chart.

Mark was attentive to everything, from how the napkins matched the centerpieces to ensuring that the cake was perfect.

“This is going to be the best day of our lives,” I told him as we finalized the guest list.

“It will,” he said, squeezing my hand. “I can’t wait to see you walk down the aisle.”

And I believed him. I believed in us. We were the perfect team, and nothing could go wrong.

Little did I know, the wedding we so lovingly planned would turn into a moment I’d wish I could forget.

The day of the wedding had finally arrived, and I was filled with excitement.

As I stood in front of the mirror, I couldn’t stop smiling. This was it. This was the day I’d dreamed of for so long.

When I walked into the venue, the energy was electric. Everyone seemed to be having a wonderful time, laughing, chatting, and soaking in the atmosphere we’d worked so hard to create.

Mark greeted me at the entrance with a kiss on the cheek.

“You look stunning, Har,” he said, his voice full of admiration.

“And you look dashing yourself,” I replied with a grin, taking in his crisp suit and the way his eyes sparkled.

Everything felt magical until Melissa grabbed the microphone.

“Alright, everyone!” she called out, her voice cutting through the chatter. “I have a little surprise for the happy couple! I’ve been planning this for weeks, and I promise it’s going to be so much fun!”

I looked at her with wide eyes. I hadn’t heard anything about a surprise game.

“Melissa, what’s this about?” I asked, walking over to her.

“You’ll see!” she said with a mischievous grin. She waved to a man in the corner, who wheeled in a small machine with wires and sensors.

“What on earth is that?” I asked, my curiosity piqued.

“It’s a lie detector!” Melissa exclaimed, beaming. “I saw this online and thought it would be a hilarious wedding game. You and Mark will answer a few fun questions while hooked up to it. Trust me, everyone’s going to love it.”

I glanced at Mark, who gave me a skeptical look but shrugged.

“Why not?” he said. “Let’s give them a show.”

“That’s the spirit!” Melissa exclaimed, clapping her hands. “Come on, let’s get started.”

The technician hooked us up to the machine, and Melissa began with lighthearted questions.

“Mark,” she said with a smirk, “have you ever eaten the last slice of pizza and blamed it on Harlene?”

He laughed. “Yes,” he admitted, to a chorus of laughter from the guests.

Next, it was my turn.

“Harlene,” Melissa asked, “have you ever secretly binge-watched a show without Mark?”

“Guilty as charged,” I said, grinning as the detector beeped to confirm I was telling the truth.

The questions continued, each one sillier than the last. Guests took turns coming up with their own, like, “Have you ever lied about liking your partner’s cooking?” or “Did you ever have a crush on a celebrity while dating each other?”

The air was filled with laughter, and I thought this might actually be one of the most memorable moments of the day.

Then Uncle Sam stood up. His usually jovial face was deadly serious as he walked toward the mic.

“Now it’s my turn,” he said, his voice low and deliberate. “Mark, did you ever cheat on my niece?”

Wait, what? I thought. Where did that come from?

I stared at him in silence, while the murmurs filled the air.

Mark chuckled nervously, looking around at the stunned faces.

“That’s a ridiculous question, Uncle Sam. I don’t think I need to dignify it with an answer,” he said, trying to wave it off.

But Uncle Sam wasn’t smiling.

“I think you should, Mark,” he said firmly. “If you’ve got nothing to hide, what’s the harm in answering?”

I felt my heart pounding in my chest.

“Mark,” I said, trying to diffuse the tension, “it’s just a game. Let’s not ruin the mood, okay?”

Mark turned to me, his jaw tight. “Exactly. It’s just a game, and this question is out of line.”

But the look in his eyes gave me pause. There was no humor there, no easy confidence. He looked… defensive.

I tried to reassure myself. This was Mark, my Mark. The man I’d trusted and loved for five years. There was no way he’d cheated on me. Right?

But Uncle Sam wasn’t backing down. “Why not answer, then? If it’s absurd, prove it.”

Mark clenched his fists, his face hardening. “Because it’s insulting, that’s why. I don’t owe anyone an answer to something so ridiculous.”

I glanced around the room, noticing the growing unease among the guests. The whispers, the exchanged glances. My pulse quickened. Why was Mark reacting this way?

“Mark,” I said softly, reaching for his hand. “Answer it so we can move on.”

But he shook his head. “No, Harlene. I won’t dignify this with a response.”

His response told me something wasn’t right.

“Mark,” I said, my voice trembling, “if you don’t answer, I’m not sure I can go through with this wedding. I need to know there’s nothing to hide.”

He looked around and then sighed.

“Fine,” he said, glaring at Uncle Sam. “No, I have not cheated on Harlene.”

Uncle Sam looked at the technician. “He’s lying, isn’t it?”

The technician quickly analyzed the results and nodded. “It looks like a lie.”

The gasp from the crowd was deafening.

“What?” I whispered. How is this possible?”

Uncle Sam smiled.

“Is there anyone in this room with whom you cheated?” he asked.

Mark looked like he’d been cornered. “No,” he said flatly.

“Another lie,” the technician said promptly.

I couldn’t believe it.

“Who, Mark?” I asked. “Who did you cheat on me with?”

He didn’t answer.

That’s when I noticed Melissa, my sister, shifting uncomfortably. A horrible thought crept into my mind.

“Was it her?” I asked, pointing at Melissa. “Did you cheat on me with my sister?”

Mark froze. He looked at Melissa before his gaze locked with mine.

“Tell me Mark!” I insisted. “Was it her? Melissa?”

Mark looked at the ground and said what I didn’t want to hear.

“Yes,” he said.

The machine didn’t need to confirm it, but it did. Truth.

The silence in the room was deafening, broken only by my shaky breath. My mind raced as I stared at Mark, then at Melissa, who looked like she wanted to disappear into the floor.

Before I could even form a question, Uncle Sam cleared his throat.

“I wasn’t going to say anything today,” he began, his gaze fixed on Mark. “But I saw you two together a few weeks ago. I was at the mall, grabbing lunch, when I spotted you, Mark, holding Melissa’s hand. I thought maybe I was imagining it until I saw the way you leaned into her. The way you touched her cheek.”

He paused, shaking his head in disgust. “It wasn’t how a future brother-in-law behaves with his fiancée’s sister. I hoped I was wrong, but something told me I wasn’t. So, when Melissa showed up today acting nervous and twitchy, I decided it was time to find out the truth.”

His words were like knives, cutting through whatever illusion I’d been clinging to. I looked at Melissa, whose face was streaked with tears. “Why?” I whispered, barely able to speak. “You’re my sister. How could you?”

“Harlene, I…” she started, but her voice cracked, and she couldn’t finish.

Then, I turned to Mark. “You didn’t just betray me. You betrayed everything we built together. How could you do this? Why?”

Mark looked away, unable to meet my eyes. “I made a mistake,” he muttered, as if that was supposed to erase the pain he’d caused.

My chest tightened, and my vision blurred with tears. I couldn’t forgive Mark. I knew cheating wasn’t just a mistake. It was a choice, and one I could never accept.

Without another word, I ripped off the wires from the lie detector and walked out, leaving behind the man I thought I knew, the sister I thought I could trust, and the wedding that would never be.

Some betrayals leave scars too deep to heal, and this was one I couldn’t ignore.

I Recognized My Bracelet That Went Missing a Month Ago on the Wrist of the Nurse Taking Care of Me in the Hospital

The moment my eyes landed on the delicate gold bracelet wrapped around Stephanie’s wrist, my breath caught in my throat. I knew that bracelet. I had spent weeks searching for it and was convinced it was lost forever. But now, it was on the wrist of the nurse taking care of me.

Life had been good before I ended up in the hospital.

I’d been married to Toby for three years, and we were living a happy life.

I worked as a consultant in a clothing store, and he had a stable job in finance. It’s not like we were rolling in money. We had enough to live comfortably.

Most nights, Toby came home exhausted. He didn’t even have time to ask me how my day went. But honestly, I never complained.

I knew he was working hard for us.

One evening, as we sat on the couch, I held his hand gently.

“I can’t wait until we have our own place,” I murmured.

“Yeah,” he sighed. “I just need a little more time to save up. You know how expensive houses are right now.”

“I know.” I smiled. “But when we finally get it, I want a big kitchen. And a backyard.”

“For a dog?” he teased.

“For a baby,” I corrected with a grin.

His expression softened, and he kissed my forehead. “We’ll get there.”

I believed him.

When he left for a work trip that Friday, I didn’t think much of it. His job required travel, and I had grown used to it.

I figured I’d use the weekend to deep clean the apartment.

Little did I know it was not the right decision.

I was dusting the top shelf of the hallway closet when the ladder wobbled beneath me.

For a split second, I was weightless. And then I was falling.

The impact was instant. A sharp, searing pain shot through my right leg, unlike anything I’d ever felt before. I gasped and my vision started blurring as I struggled to move.

Gritting my teeth, I reached for my phone, barely managing to swipe the screen. My fingers trembled as I dialed 911.

Minutes later, the paramedics arrived. The pain was unbearable as they lifted me onto the stretcher. I could barely keep my eyes open as they wheeled me into the ambulance.

At the hospital, the X-ray confirmed what I already suspected. I had broken my leg.

“You’ll need to stay here for a few days,” the doctor informed me after wrapping my leg in a cast. “We need to monitor the swelling before we can send you home.”

The moment he left the room, I grabbed my phone and called Toby.

He picked up immediately. “Kate? Hey! How’s my beautiful wife doing?”

“Toby,” I whispered. “I… I broke my leg.”

“What?” His tone shifted from playful to panicked. “How? What happened?”

I exhaled shakily. “I fell off a ladder while cleaning.”

“Jesus, Kate.” I heard rustling on the other end like he was moving around. “I’m coming home. I’ll cut my trip short.”

“No, you don’t have to—”

“Don’t even argue. I should be there with you.”

Tears pricked my eyes. “Okay.”

I was still on the phone with him when the door opened. A nurse walked in.

I quickly told Toby I’d call him later and hung up.

“You must be Kate,” the nurse said. “I’m Stephanie. I’ll be looking after you while you’re here.”

“Nice to meet you,” I said, forcing a smile through my discomfort.

“Don’t you worry about a thing,” Stephanie assured me. “We’re going to take great care of you.”

I let out a breath, nodding. She seemed kind.

I had no idea that in just a few days, this woman would shatter everything I thought I knew about my life.

At first, Stephanie was wonderful.

From the moment she started looking after me, she made sure I was comfortable. She checked on me regularly, adjusted my pillows when I couldn’t move properly, and even brought me an extra blanket when I mentioned feeling chilly.

“You must be tired of hospital food already,” she joked one afternoon as she handed me a tray. “I wouldn’t blame you if you refuse to eat this.”

I laughed. “I wasn’t going to say anything, but yeah… this is not exactly gourmet dining.”

She grinned. “Don’t worry. I’ll sneak you something better if I can.”

Over time, we started talking about our lives.

“So,” she asked one evening as she fluffed my pillows, “do you have kids?”

“Not yet,” I admitted. “My husband and I want to buy a house first, then start thinking about kids.”

She nodded. “That’s smart. Kids are expensive.”

I smiled. “What about you? Are you married?”

She shook her head. “No, but there’s someone in my life. We’re dating. Nothing serious yet.”

“Do you think he’s the one?” I teased.

“Maybe,” she shrugged. “He’s great. You know, the kind types. He’s been spoiling me lately.”

“That’s sweet,” I said. “It’s nice when someone makes you feel special.”

The next day, when Stephanie walked into my room, something caught my eye.

A bracelet.

It was not just any bracelet. It was a delicate gold chain with a small heart charm, and it looked just like the one my grandmother had given me.

The same bracelet that I had lost a month ago.

At first, I thought it was a coincidence. But then, as Stephanie rested her arm on the side table while adjusting my IV, I saw it up close.

The tiny engraving on the back of the heart charm had a little smiley face.

My grandmother had requested the jeweler for that smiley. She told me it was especially for me.

Suddenly, I felt lightheaded.

How is this even possible? I thought.

I had looked for it everywhere, and I was convinced I had misplaced it. But now, it was there. On my nurse’s wrist.

“That’s a beautiful bracelet,” I said, forcing a smile. “Where did you get it?”

Stephanie glanced down, then smiled. “My boyfriend gave it to me.”

A chill ran down my spine.

“That’s sweet,” I said. “When did he give it to you?”

“A month ago.”

My fingers gripped the hospital blanket.

Suddenly, memories flooded back.

I had been getting ready for a party. I had done my makeup and reached for my jewelry box when I realized my bracelet was missing.

“Toby, have you seen my bracelet?” I asked, rummaging through the drawers.

“You probably left it somewhere,” he said.

“But it’s always in my jewelry box.”

He sighed, glancing at his watch. “Kate, we’re getting late. Just wear something else.”

His reaction had felt off at the time, but I let it go, thinking I had misplaced it.

Now, as I stared at the bracelet on Stephanie’s wrist, the pieces started clicking into place.

Toby had taken it.

And he had given it to Stephanie.

Before I could say anything else, I needed to be sure.

My heart pounded as I reached for my phone. I quickly scrolled through my photos until I found one of Toby and me from our anniversary dinner.

Then, I turned the screen toward Stephanie.

“Is this your boyfriend?” I asked.

She glanced at the photo, her smile lingering for a brief second before fading.

“How do you know him?” she asked, confused.

I swallowed the lump in my throat. “Because that’s my husband.”

Silence.

Her eyes darted back to the bracelet on her wrist, and then back to me.

“Wh-what do you mean? Your husband?” she asked. “I… I don’t understand.”

“I’m saying that Toby is not just your boyfriend,” I explained. “He’s my husband. And that bracelet? It was mine before he stole it and gave it to you.”

Stephanie took a shaky step back, crossing her arms. “That… that can’t be true. He wouldn’t do that to me.”

“He’s been doing it to me for months,” I said bitterly. “You just didn’t know.”

“No…” she said. “He told me he was single. He never mentioned a wife.”

I almost laughed. “Of course, he didn’t.”

Stephanie’s breathing grew uneven as she processed everything. Then, her expression hardened.

“I can’t believe this,” she exhaled sharply. “I can’t believe I trusted him.”

I met her gaze as a plan formed in my mind.

“If you’re willing to help me, we can make him confess when he comes here tonight,” I suggested. “He said he’d be back from his trip today.”

“What do you have in mind?” she asked.

“We call the cops,” I said. “And when he comes in, we make him admit to what he did.”

“Alright,” she nodded. “I’ll do it.”

Then, she took the bracelet off her wrist and handed it to me.

“It’s yours,” she whispered. “Keep it.”

***

That evening, Toby arrived at the hospital. He looked frantic and exhausted as he rushed to my bedside.

“Kate, baby, I got here as soon as I could,” he said, brushing his hand over mine. “How are you feeling?”

I studied him carefully.

He was the same man who had been my husband for three years. The man I had trusted. The man who had stolen from me and lied straight to my face.

Before I could respond, the door opened.

Two police officers walked in, followed by Stephanie.

“What’s going on?” Toby asked, his face filled with confusion.

Stephanie stepped forward and pointed at my bracelet. “She says you stole that from her and gave it to me.”

Toby’s brows shot up. “What?”

The officer looked at me. “Ma’am, is it true?”

Before I could answer, Stephanie’s voice cut in. “No. It’s not true. I don’t have any bracelet. I don’t know why she thinks her husband is interested in me.”

I couldn’t believe it. Was this the same woman who had just agreed to expose Toby? The same woman who had seemed just as betrayed as I was?

“See?” Toby let out a nervous chuckle. “This is ridiculous. I don’t even know what this is about.”

I was still reeling from the betrayal when I heard it.

A sigh.

Then, a quiet, shaky voice.

“Alright… I did it.”

I snapped my head toward Toby, watching as he ran a hand down his face, his expression defeated.

“I stole the bracelet,” he admitted, his voice heavy with guilt. “I took it from Kate’s jewelry box and gave it to Stephanie.”

“Toby!” Stephanie shouted. “No!”

But he ignored her.

“I met her at a bar one night after an argument with Kate,” he confessed. “It wasn’t supposed to be anything serious, but… things happened. I took the bracelet because I thought Kate wouldn’t notice. But she did.”

I heaved a sigh of relief.

The officers exchanged glances before one of them spoke. “Ma’am, do you want to press charges?”

I looked at Toby. He wouldn’t even meet my eyes.

“No, officer,” I said. “I don’t want to press any charges.”

Toby’s head lifted slightly in surprise.

“I’m not going to ruin your life,” I said. “But I’m not going to stay in it either.”

Once the officers left, I turned to Stephanie.

“What the heck was that?” I yelled at her. “What were you trying to do?”

“I’m… I—”

“Get out!” I shouted. “Just get out of this room. Now!”

She hesitated, but then she nodded and left without another word.

Toby stepped closer and tried to apologize. “Kate, I—”

“Don’t.” My voice was calm. “Just leave.”

His eyes filled with regret, but I didn’t care anymore.

He walked out, and that was the last time I saw him. Our divorce was finalized soon after.

Leaving him wasn’t easy. Letting go of the life I had built wasn’t easy. But I had no choice. I couldn’t stay with someone who had betrayed me so deeply.
