Should I be friends with benefits with my ex?

I'd say no!. Friends with benefits can work usually only with someone who you haven't been in a relationship with.

And anyway, after what he did, he doesn't deserve it. You can find a partner who at least deserves it. ;-)

No way! Sorry to say it but it sounds like he was just with you for sex. There are guys out there who'll give you more than that. I'd stay well clear of him.

So sorry to hear that, you should definitely break it off with him because he is just using you, make your heart strong and walk away. Don't let yourself being used.

I'm sorry you gave it up to a loser, but learn from this and don't give in to his loser antics........no sex for him...........I think it would be okay for FWB ONLY if the break-up was mutual and you still wanted sex.........but that all depends on your morals, and i'm thinking this is not that situation.

I agree with person1. You should not be anything at all with this guy. He obviously doesn't care enough about your feelings to break up with you like that and now he just wants to sleep with you with no strings attached, knowing that you still have feelings for him. Cut him off and let him go. Best of luck to you! :)
