Now what did we learn?..

WTF you don't even ask questions first? You see him with a girl and you automatically assume? Good work, now he's probably going to be an asshole to the next girl he dates because you tainted his view of women.

Wow, you sound insane...

You bitch, this is why we can't have nice things.

WOW. I hope he dropped your jealous ass. No one needs the drama. And maybe you shouldn't jump to conclusions next time, ya?

you are a dumb ****.

for some reason, all women assume that a man is cheating on her if he's seen with any other woman. this FML fails so hard, and no one on here should even think twice of defending OP's actions

wow obviously someone's got deeper issues

He was simply with her and you assumed that he was having a sexual affair? My god, woman. That is terrrible judgment. Don't get with anyone else until you learn to have some basic levels of trust. Sounds like if that had been a platonic friend rather than a cousin, he would've had a hard time proving to you that he wasn't fcking her.

Insecure much? You don't deserve any kind of boyfriend if you break up with him because of a conclusion you've jumped to without even talking to him. :/
