Here's what people said:
This shocking find:
"I found him with another woman in bed in our guest room. He was in there, and locked it while I was sleeping. That bed happened to be my childhood bed."
This Facebook find:
"He was late to the ultrasound screening of our future child. I checked his Facebook and there was someone all over him in all his tagged photos. They were also making out in the background of one photo."
And this one, too:
"He left his Facebook open. I saw his messages. He was telling his ex he was single and invited her to a wedding."
This sister-in-law's confession:
"She confessed to her mom. Then, mother-in-law called her other daughter and told her. Sister-in-law then called me and told me. She let me listen in on a three-way call to her mom and tried to convince her mom to tell me. But she refused, which basically confirmed it."
This smoky situation:
"I don't smoke weed. My husband asked me to go get his stash for him. I found a note from the nanny to my ex saying she was in love with him, and she was so happy for the time they had together. Obviously she thought he would get the weed instead of me."
"I came home from work early. When I got out of my car, I saw her peek through the blinds to see who was outside. I walked in the door to find her coworker on the couch, obviously uncomfortable and clothes messy, and her locked in the bathroom. He was an MMA fighter. They started dating the next day."
This iCloud indicator:
"She had also lent me her iPad, and it was synced to her phone. So I saw lots of texts between her and someone else over that weekend. They were talking about running away together."
This affair with undeniable evidence:
"I found videos of him hidden on one of our computers and found out he was having booty calls in our apartment while I was at work."
And this one, too:
"I found a used condom on the bathroom floor. I just emailed him a 30-day end-of-tenancy notice. I own the house."
This app-solutely heartbreaking situation:
"I found out he had signed up for a bunch of apps, such as Ashley Madison, Tinder, and Bumble. He would message mutual acquaintances."
This hotel worker's discovery:
"My buddy works at a hotel and called me saying that my wife just checked in with another guy."
This dumb cheater:
"He took a phone call from her in front of me. And because, I guess, he thought he was being slick, he started flirting with her in front of me."
And lastly, this genius wife's idea:
"A friend of mine was suspicious of her husband cheating, as he went to 'play soccer with friends' way too often. He always came back already showered, as he would sweat playing. One day, she sewed his soccer socks together. And when he came back all showered, she saw the socks were still sewed. So he wasn't playing soccer at all."
