rot in hell, idiot.

This is a delicate situation. You basically need to crawl back to him and admit you were stupid and jumped to conclusions, all because you forgot that particular bra. Then you probably need to have a serious discussion about trust, and whether he has given any indication he's possibly cheating, or whether you simply have a bit of paranoia.

I mean on the one hand, if OP had ended the fml at 'my boyfriend sent me a picture of a bra he claimed I left at his house. I know every single bra I own, and it wasn't one of them' I ma pretty sure the fml community would be on their side. There is obviously context in terms of breaking up with someone like history, whether you believe them etc. and it is unlikely the bf would show her a pic of another girl's bra (had he been cheating) unless he was really bad at cheating. But I think if this had been posted before OP remembered they'd lost the bra, we would have been behind her which would make the fingerpointing for OP breaking up with her bf unfair.

You "lost" said bra? You have big problems then thinking a guy is cheating on you.

So did you get your bra back?

Well, aren't you a little hothead. Calm the h*ll down or you'll have bigger problems than losing a boyfriend.

That is why the saying goes, don't count the chicken before they hatch! You should have thought about it!

Poor lad @op please apologise and tell him the truth these types of things will change him for the worse since he was naive and innocent enough to send you a bra picture expecting no backlash

women like you turn perfectly normal truthful loyal guys into insecure whimps that act like cheaters out of fear of getting dumped over some stupid misunderstanding..you need to gain self confidence and love yourself more, only than will you be ready for a good relationship. if he is the one for you, you will be together. but you really have to apologize for acting so harshly and unjustly accusing and suspecting him.

You ****** uuuuup. YDI all the way.
