The passenger seat of his truck was reclined all the way back and her sunglasses were still in the cup holder.

His mom called me to ask if we could put the cat inside while we were at her place, she saw my ex’s car in her driveway on her Ring camera and saw “us” go in. I was not with him, as he told me he was going to the grocery store. Turns out he was taking his side piece to his Mommy’s house while she was at work. She promptly sent me the video. She may have been a not so great MIL but she doesn’t play well with cheaters

My fiancée got drunk one night and started talking about how much she enjoyed the sex we had last night. I was working last night….

He received a letter in the mail for Christmas with her panties in it

My Auntie heard from her hairstylist that her husband was cheating on her. She found the address of the affair partner and went on google earth. Her husbands truck was in the driveway when google earth had taken the picture.

Wife went on a business trip that she SWORE was on her own. Called her hotel room late one night, no answer. Called the hotel front desk and asked if they could connect me to name-of-someone-she-worked-with, and they put me right through. He answered the phone, and when I told him to put her on, he handed it to her.

He left his phone in the bathroom and she texted “I’m pregnant what are we gonna do?”

My ex lived in an apartment 15 miles away. The night in question at approx 1am, a neighbor of hers accidentally fired a round while cleaning his gun. The bullet went through their mutually shared wall, through another, and lodged in her refrigerator. The cops were called by another neighbor and she ended up with a police report and stuff. I ended up reading the police report and it mentioned her and a guys name I didn’t know were reported in bed at her place at the time of the accidental discharge. She confessed right there she had a f**k buddy. 1.5 yr relationship down the drain.

His mom told me.

I was at work and a buddy was scrolling through match dot com while we chatted. Up pops a picture of my girlfriend. In my living room where she lived. I went home, logged into the computer and pulled up her profile. Shut off the screen saver and went up to my room. I heard her come in, start crying and leave again. The next day when I came home from work all her s**t was gone.

My boyfriend at the time wished me happy birthday randomly one day in July. My birthday is in April. He tried to play it off as a joke when I was confused, but I later found out that he was still seeing the woman that he claimed was his ex, and he had our birthdays and other info in his calendar to try to keep everything straight. He slipped up and wished me happy birthday on her birthday.

One time when I knew my ex was cheating and I was trying to get him to admit it so I could break up with him, he started sending screen shots of our texts to show me “how crazy I was being” - one of those screenshots had the little box at the bottom of the text chat of his camera roll open I guess while he was sending me the screenshots. There was a picture of another girl, pics of him at her house, etc. I actually laughed out loud when I saw it-something about him trying to convince me I’m insane while simultaneously sending me evidence by accident was weirdly hilarious.

A colleague of mine was out doing shopping, when she ran into a family friend who happens to be a police officer. She asked how he was doing and he said he was good but that he was tired because they were out all night looking for a car that fled from a known drug and p********e spot. He mentioned that they never found the suspect but that during the chase the suspects car hit a curb and lost its front bumper so they were on the lookout for a white sedan without a front bumper. Later that evening her husband returned from an “out of town” business trip without his front bumper. He had a white sedan.

The dog was playing with a notebook, didn’t look like a diary or anything. I pick it up, first page had a list of names, I didn’t recognize some of them. Her ex was before my name, my name was before someone else.

ex and i shared a bank account. one day the bank called me to approve an over limit amount… at an escort service in Nevada.

Honestly, I had a series of dreams of her cheating on me. I started to snoop lightly and found texts, emails, pictures of it within a short period of time. I guess my unconscious picked it up?

I was driving, he was sitting in the back with the baby. I could see his phone screen in the baby mirror.

Many years ago I was visiting my GF in her city, we were long distance. She had a roommate, we'll call her Sandy, who was one of her best friends. One night, we had all gone out with some other people, drank, had a good time, and we were back at the apartment asleep. Sandy had still been out when my gf and I crashed. I wake up to my GF's phone ringing. Quickly grab it to make it stop, screen says Sandy is calling. I didn't hesitate at all, answered her phone, thought maybe Sandy was locked out or needed a ride who knows. On the other end of the phone was a man, looking for my GF. I'm like, who the f**k are you, he, likewise wants to know who the f**k I am. My girlfriend finally wakes up to me basically yelling at this dude on the phone. One huge messy fight later. "Sandy" on the phone was the guy she was always texting. And regularly f*****g, mind you. She saved him as her best friend's name so she could freely text in front of me so I wouldn't be suspicious. Pretty slick tactics.

Through an iPad lol. Apple can sync messages between devices, but at the time in 2012ish, it was a novel thing so not everyone had two Apple devices nor allowed them to sync. My ex did. While on her iPad watching some dumb video, I saw a message pop up from a girl named “Leslie” (not her real name) asking what song my ex wanted to hear next time. It was kind of weird, but I assumed they met at some girls night out thing recently and became new friends, so whatever. Until she started replying from her phone in another room with a selfie she took of her half naked saying something like “here’s some inspiration.” Turns out “Leslie” was a dude. Not just some dude, but a skinhead who wore a kilt and played the bass in some cheesy metal tribute band.

We went to the same college. He was emailing me an assignment to look over for him to make sure it looked professional. I noticed the email was in a woman's name. He had forgotten to let her log off of his computer. That made me suspicious, so I waited until he was asleep, went on his phone and got solid proof, sent it to myself. Kicked his a*s out of bed and to the curb.

In an argument she insisted that I randomly changed my opinion on Mike and Ikes because I used to despise them and now I suddenly love them? She was going on about something related to me hating the texture (chewy candy is my favourite) and wouldn't drop it. I always absolutely loved Mike and Ikes, even though they're overly sweet and kinda cheap, they're delicious. They're an import item here in the UK you have to buy somewhere like Costco, so it's often a rare and pricey treat. So obviously very strange that my girlfriend of seven months doesn't know this about me, or has it wrong. I thought she was either psychotic or trying to gaslight me, but it was worse than that. The other thing is though, I realized when hanging out with one of my coworkers he said that he was absolutely disgusted by jelly beans and all other chewy candy when I offered him some. That's when it hit. She got us mixed up, and she'd been f*****g him the entire time. He didn't know either, so we broke up with her and are still friends to this day. Sometimes he reads my posts so hey Jason!

My ex said she wanted to go out by herself on a Saturday afternoon. Said she was gonna go fishing. I stayed at her parents', and started to get worried when it got dark and she wasn't back yet. So I called her, and there was silence on the other end. She said she was in a park, but the silence clearly felt like she was indoors. Suddenly I hear what sounded like a small dog barking in the background, and I could swear it echoed?? She said it was someone walking a dog. I said ok, kinda in denial. I knew she was lying, just didn't know why. Fast forward to a week later, I found some weird parking tickets assigned to our car's plate number in an app the city provided for parking purposes. Strange hours, car parked for way too long in a parking meter downtown, always the same spot, next to a residential apartment building, early in the morning and during work hours. And during the afternoon she said she had gone fishing. I went on to look up her Facebook to find out who she was seeing behind my back, found her boss' profile, and lo and behold, he had a small dog with him in one of the pics. The same kind of dog I heard on the phone a week before. I also found a picture taken right in front of the building where our car had gotten those parking tickets. And that was it. When I confronted her, she started a very weird routine of admitting and then denying it, which drove me crazy for months. I forgave her, but it kept happening, and eventually it led to a divorce

The woman he was cheating on me with looked at my LinkedIn profile. They’d worked together, so I asked him about it, and knew instantly from his reaction what was going on.

My ex wife talking in her sleep

I found a physical photograph between his mattress and box spring of another woman in a compromised position.

A girl I hardly knew called me in the middle of the night and said she had just seen my long/term boyfriend’s car at the trailer house of a gal who was newly divorced

Needed to send my mom something for Mother's Day. Was thinking out loud when my husband suggested a specific online gift basket company. That man, to my knowledge, had never ordered a gift basket in his life. I bought all the gifts for our family and our business. Went into Quickbooks and searched for the name of the company. Found a Valentine's gift basket sent to a bartender at a place we sometimes stopped off to together after work.

Drove past a motel as I was on my way home from visiting my parents in another city. Some of the motel room doors faced the freeway, and just as he was stepping out of one of the rooms, I happened to glance over as I drove by on the freeway. He was wearing his distinctive motorcycle suit, and his motorcycle was parked right there. He looked back into the room and was talking and laughing just as he stepped out/just as I saw him, so I didn’t think he saw me or my car. I never revealed to him that this was how I found out, but he confessed when I said I knew he’d been unfaithful.

In a dream. Very early in the relationship I had a dream his ex, who I never met and had moved overseas, was pregnant. I told him about the dream, he went white as a sheet, mumbling something about how “crazy” the dream was. Two days later he admitted he had been in communication w his ex, who had reached to let him know she was pregnant and keeping the baby. They had been talking for weeks, she had even sent him a creepy drawing of them as a happy family.

I walked in on him with our landlord. It was also how he came out of the closet. Super fun.
