My Husband Returns 'From Work' Wearing a Different Shirt — My MIL Gave Me Golden Advice That Taught Him Faithfulness

A devoted wife becomes suspicious when her husband starts returning home in a different shirt every evening. He denies it, but her MIL's advice helps her devise a clever test to prove it. But nothing could've prepared her for the heartbreaking reason behind her husband's odd behavior.

At first, I thought I was imagining things when my husband started returning home in a different shirt from the one he'd left in that morning.

Ten years of marriage and three kids under 10 can make your brain foggy, especially when you're the one doing most of the parenting.

Then I thought there must be a simple, rational explanation. Adam had always kept a spare shirt or two at the office in case he spilled coffee on himself.

But day after day, he came home in a different shirt from the one he'd worn when he left in the morning.

It made no sense, and the curiosity was eating me alive, so I asked him about it one evening.

"I'm not changing my shirt. You're imagining things, Erin," Adam said, his voice clipped, his thumbs still busy scrolling on his phone. "Seriously, stop overthinking. You sound paranoid."

That's when my confusion about his new habit turned into burning suspicion. I wasn't paranoid, and I was certain I wasn't imagining things either. Adam was trying to gaslight me, but why?

That night, I lay in bed staring at the ceiling, Adam snoring softly beside me, his phone face-down on the nightstand. I couldn't shake the feeling that something was wrong.

He hadn't always been like this. Dismissive. Cold. Distracted. When we first got married, he used to call me in the middle of the day just to hear my voice. Now, I was lucky if I got a text asking what was for dinner.

And now the shirt thing… what was I going to do about it? My head spun. I barely slept that night, but by morning, I realized exactly who I needed to turn to for help.

After Adam left and I'd gotten the kids off to school, I texted Nancy, my mother-in-law.

It might seem strange to ask my MIL for help with her son's odd behavior, but Nancy and I had always been close. I lost my parents when I was young and Nancy had become like a mother to me. I could tell her anything, and she'd always listen.

"I need your advice," I messaged her, clutching my coffee cup so hard my knuckles went white. "Something weird is going on with Adam. In the morning, he leaves for work wearing one shirt, but comes home in the evening wearing a different shirt. He's obviously changing somewhere, but denies it!"

Almost immediately, it showed that Nancy had read the message. I stared at my screen as I waited for her reply.

"I'd sew a tiny thread into his shirt seams to check," she replied. "Then you know for sure he's changing his shirt and can provide proof when you ask him about it."

It sounded ridiculous. Childish, even. But Nancy wasn't one for pointless theatrics. If she thought it would work, I trusted her.

"Okay," I sent back to her. "I'll do it."

The next morning, I picked out one of Adam's favorite shirts, a blue button-down with small white stripes.

I threaded a needle with the smallest strand of red thread I could find, my hands trembling the entire time. I sewed it into the seam where it wouldn't be noticeable. When Adam got dressed for work, I handed him the shirt and watched him put it on.

As Adam kissed me goodbye and headed out the door, I watched him leave like I was sending him off to battle. Today, I'd prove he'd been changing his shirts, but the next part would be discovering why he'd been doing this, and why he'd lied about it.

All day, I felt like I was holding my breath. When Adam came home that evening, I couldn't hide my reaction. He walked in wearing a pale blue shirt with no stripes. Similar to the one he'd worn that morning, but not the same.

He changed his clothes and settled on the sofa to watch TV. I hurried upstairs and fished his shirt out of the laundry hamper.

I then sat on the bed, my heart pounding, and searched for the thread I'd sewn into the seam that morning.

It wasn't there. I'd known it was a different shirt, but now I had proof and that changed everything.

Later that night, when the kids were finally asleep, I approached Adam with the shirt he'd arrived home in.

"Where's the shirt you wore this morning?" I asked, my voice trembling.

He frowned, barely looking up from the TV. "What is it with you and my shirts, Erin?"

"I know you're lying," I said, louder now. "I sewed a thread into your shirt this morning. It's gone. Where is it?"

Adam froze, the remote still in his hand. For a moment, I thought he'd try to deny it again, but then his shoulders sagged, and he let out a long, heavy sigh.

"Fine, I admit it. I have been changing my shirts."

"Why? And why have you been lying about it?"

"Because… I met someone," he said, his voice flat.

The words punched the air from my lungs. "What? You've been having an affair?"

He nodded. "With Karen. It just happened. I didn't want you to notice her scent on me so she's been giving me fresh shirts from the clothing store she manages."

Karen. Our neighbor. I couldn't speak. I couldn't breathe. My world tilted, the ground beneath me threatening to swallow me whole.

"But I guess it's time I stopped living a lie," he continued, finally meeting my gaze. "I'm sorry, but I'm filing for divorce. I'll visit the kids twice a week."

I stood there, motionless, as he walked away. Of all the scenarios I'd pictured, Adam leaving me wasn't even on the list. I felt completely unmoored.

I dropped down onto the sofa as tears filled my eyes and texted Nancy.

"Adam's having an affair," I typed. "That's why he's been changing his shirts. He wants to get divorced. What am I going to do? What am I going to tell the kids?"

"You need to stay calm and agree to the divorce," she replied.

I stared at my phone screen in shock.

"Then tell him the kids should stay with him," she added.

For a moment, I felt doubly betrayed. It seemed to me like Nancy was siding with Adam and cutting me out of their lives, but her next message explained everything.

"Trust me on this. It will ruin his plans because he's expecting a fight, not this. And believe me, his mistress is certainly not ready to suddenly become a mother of three kids."

My jaw dropped. Nancy's plan was ruthless. Cold, even. But as I sat there, something inside me clicked. Nancy was right. Adam and Karen thought they'd won. It was time to show them they hadn't.

"Okay, Nancy, I'll do what you say," I replied.

The next morning, I told Adam I'd agree to the divorce, but I wanted to sit down and discuss the details with him and Karen so we could all be on the same page. He was surprised, but agreed.

The café was buzzing with the hum of conversations when I walked in. Adam and Karen were already seated, their smugness radiating from across the room. I sat down and folded my hands in front of me, doing my best to seem calm.

"I've thought about everything," I said. "I won't contest the divorce, but I want to keep the house since you're the one who's leaving, not me. I also think it will be best if the kids live with you and Karen."

Karen nearly spit out her latte. "Excuse me?" she stammered.

"What are you talking about?" Adam yelled. "What kind of a mother are you?"

I then turned to Karen and said, "Sam has a lot of extra-mural activities at the moment, but I'll send you the schedule. Amanda is a picky eater, but I'll take photos of how I cut up her food and make a list of everything she does and doesn't eat. I'll also tell you how to do Mitch's bedtime dance and provide a detailed potty-training schedule."

Karen looked like she'd seen a ghost. "I — I didn't sign up to play mommy to three kids! And potty-training? There's no way."

She stormed out of the café. Adam followed her, leaving me sitting there with my heart pounding in triumph.

Two days later, Karen dumped Adam. I found out through Nancy. He had nowhere to go after Karen dumped him, so he'd returned to his parents. They weren't sympathetic.

When Adam finally came back to me, he was a broken man. He stood on the porch holding the keys to a convertible parked in the driveway. The car I'd always dreamed of owning.

"I'm sorry, Erin," he said. "For everything. Please, can we try to fix this? Mom and Dad have helped me realize I need to step up and be a better man for you and the kids."

But a car wasn't enough to erase what he'd done.

"You'll never disrespect our family again," I said firmly. "If you stay, you stay as the husband and father we deserve. Otherwise, don't come back."

Adam agreed. Slowly, painfully, we rebuilt our marriage. It wasn't perfect, but it was stronger. And through it all, I rediscovered my strength. I wasn't just Adam's wife anymore. I was Erin — a woman who refused to let betrayal define her.
