no he wasn't. the reason was just thrown in his face.

People can accept their partners having friends. People can even accept friends with benefits relationships in the past. But when you are still friends with the person, it can be too much. Especially since it was initially held back and we don’t know how it was brought up. It’s the sake reason why people aren’t always accepting of someone still being tight with an ex.

OMG, a girl with a past sex life, call the elders!

Because mature, confident people can handle that sort of information, jealous insecure people cannot.

Telling you what, that she's slept with someone else? That not all of her relationships end badly and she's still friends with past lovers? I can't see the breach of trust.

I think you have trouble separating friendship, sex and relationships. they are 3 separate things, and you can have sex with someone and not want to be in a relationship

This is different. OP turned a friend into a **** buddy, and kept him around despite getting into a real relationship. How would you feel if your partner introduced you to a friend, and told you that they get together and **** when they're both single? It's almost as though OP told her boyfriend "It doesn't matter what happens with us, because I've got him, and I didn't tell you we're occasionally **** buddies in case you scare him off." I didn't say this guy was right for leaving, but his reaction is understandable. If he'd stayed, he would have always had that little voice in his head questioning if they might be hiding their true feelings from one another, and he's just a cover while they continue denying those feelings, so he bailed before his insecurities got the better of him. Sex, friendships, and relationships may be three individual things, but combine any two, or even all three, and life can become pretty complicated pretty quickly. It would seem that OP's boyfriend didn't want to deal with those complications, while OP herself could be in denial that she wants more from her friend. If she wanted sex as a cure for the itch, as it were, why not find a one-night stand, instead of using someone she was close with and agreeing they weren't going to "label it, and make it awkward"? Just as well cross all the lines if you're going to cross one. That, or hook up with a total stranger to deal with the urge, which is the simplest option.

So are you supposed to bring a sexual resume with you to every first date? She probably brought it up because it was relevant to the conversation.
