There are few things more devastating in life than finding out your partner is cheating. With some exceptions (ie death, sickness, blah, blah) cheating is an absolute blow to morale.

Thanks to the brave souls over at AskReddit, we've compiled the wildest stories about how folks have discovered that their partner was cheating on them. Reader beware, it's not pretty. These are true stories involving real relationships.

Also, hey! If you're the cheater in a relationship and you happen to find yourself reading this... Stop cheating. Don't be that guy or girl.

My fire alarm woke me up when it was low on batteries at 5am and thought it was strange that my gf wasn't home yet (she was out drinking with her friend). I tried to call her, but she didn't answer. Thats when I remembered that we had the friends spare key. She lived like next house so I went to check and my gf was sleeping in her friends bed with some guy. If the fire alarm didn't woke me I think I wouldn't have ever known. -Kaalilaatikko

On my birthday I was with my GF and I passed out early since I had a long shift that day, and I had to drive 2h to get to her place. Woke up in the middle of the night, went outside to get a smoke, saw her doing her ex in his car in the parking lot. -Salakelmi

Came home off a deployment. Now (ex) Wife was acting really weird but I figured it was because I had been gone for a year and everything was just taking time to get reacquainted. About 3 days after I returned I had a notice from my unit stating my vehicle had 3 tickets at another base (we were in Germany) a few hours away in the past few months. When I went in to find out what the deal was all 3 had photos attached to them for speeding through a checkpoint. All 3 had my wife and some other guy. She was kissing him in the 3rd pic...he was driving my car. -1plus1equals8

He was drunk at his 21st and while joking around with his friends he started listing off all the women he’d slept with in the last year. I was standing right there and we’d been dating for two years at that point. -Fraerie

I joked about knowing she was cheating she broke down and admitted it. -Classic-Brilliant93

He sent me a pic of the dog while I was away with a text that said "look how cute she looks" like 3 weeks later I went back to the photo to show a friend and upon looking at the photo again I noticed a pair of women's boots in the background by the door. -jammersG

He apparently wrote an address wrong and the love letter he wrote was returned to our home. It was a great way to come back from vacation. -Character_Moment_689

Her other boyfriend (who I didn’t know existed) and I had a mutual friend who put two and two together and told me. I said I wanted to meet him so he called him over. We talked out some things and then called her together at my suggestion. Good times were had by all -1. -Jonaldson

Date night cancelled day-of. I decided to make it a guys night to see the new marvel movie at the time. As we entered, I saw her sitting it the theatre snuggling up with a guy. Our seats were a few rows back, saw them kiss a couple times. When we all left at the end of the movie they were exiting their aisle as we walked down the stairs. She absolutely froze when she saw me. Blocked her on everything while I’m the in parking lot. -RiddledWithEnigma

Broke up with me and as I was going though deleting her socials I noticed a post she made on her snap story that was her and a guy with a post saying "with my king", post was made two hours ago and had only broke up an hour ago. -tipedorsalsao1

My ENTIRE friend group knew about it, and I only found out after the one real homie blackmailed her into admitting it. And when she did, it was the most insincere thing ever. "It's no big deal, everyone else thinks it's ok!" and stuff like that. Suffice it to say, I got myself outta that relationship AND friendship group real quick. -Samurai294

Not really wild but my ex-wife and I owned a small business together. One day I noticed a strange email address on the office computer. Her first name and a different last name. I realized that email was still logged in so I took a peek. I found 2 years worth of emails between my ex and some dude she dated before me. So I printed out every email and had it bound in a binder ready to present to my divorce lawyer. -easy10pins

I went on a 2 week holiday and when I returned he was acting really strange. I tried to ask him what was wrong and why he was acting off. He started an argument with me, told me I was too young and insecure, asked me to leave, didn’t want to see me again. I left sobbing totally confused. Nine months later I see him walking through the city with his ex and a newborn baby… ah. Now I understand. -Keepdreamingkiddo

He sent me a photo of some girl s-ing his 'D' at the party he was at. On Valentine's Day. After cancelling his plans with me. -speckledrectum

Not me but my dad. His girlfriend at the time had been cheating on him with his friend, who didn’t know they were in a relationship. My dad found out when his friend told him he was gonna propose to her. -Roguewalker72

Her parents told me. -TuPockets

My 9 year old son told me that there were strange men in the house when I was away working. She'd been at it for years. It's horrible to deal with at the time, but honestly, it's such a relief to be rid of such a toxic mess. -beerdybeer

One of her friends was a photographer and wanted to do 'tasteful nudes' which apparently includes penetration! And multiple days of getting the right shot... We had a shared Google drive, which her friend didn't know we shared. -PumaRevived

She demanded to read all the messages on my phone, I said no problem but only if I could read the messages on hers. She had forgotten to delete a message from a guy saying "All we ever do is hook-up, can't we hang out some time?" There was nothing on my phone. -forcekin69
