There are pros and cons to walking in on a partner cheating on you. Cons: heartbreak, betrayal, a scarring memory, and potentially losing the ability to ever fully trust someone again. Pros: you can break up with them, move in with three roommates of the opposite sex, have an on-again, off-again relationship with one of those roommates, and become the plot of the sitcom New Girl. Also: you now have an excuse to absolutely destroy someone's car with a sledgehammer. And let's be honest, that part seems fun?!
Someone asked Reddit: "have you ever walked in on your husband, wife, boyfriend, or girlfriend having sex with someone else? What did you see & What happened?"
1.) From throwaway12934509834:
It was a weeknight. I woke up a few hours early (4 AM-ish) to play a few video games before work. My wife (of 6 months) is not in bed with me. I call her phone, and hear it ringing in the guest room. I peek inside, and saw her in the throws with one of her male friends that I had met the previous night. They did not see me, so I closed the door. I went out to the garage, and returned with a claw hammer. I sat against the door for almost an hour, deciding what to do with my life. After that, I kicked in the door, gave them both a stare that I can only hope froze their blood, then walked out and drove to work. I left her that night, and I kept her hammer. She begged me to stay with her. It was winter, and I did have to live in my car for almost a month, but it was still the best decision I ever made.
