It's painful at first but it does get better. First off, you screwed up getting involved with a guy that had all of that drama going on in the first place. Second, he's a stupid dick for abliging you when he wasn't over his own shit. You're loveable, worthy of love, and there's nothing wrong with you. Just take some time and space, and work on yourself. This situation sucks, but remember that there was no divorce, no mortgage, and no kids involved. It could have been worse... much worse. Obviously he's not happy, and has no business being in a relationship in the first place. You seem like a sweetheart and you can do much better. But, don't sit here and say "I can't trust men, when you made the conscious choice to go out with a train wreck.

Have you tried talking with him? I know you are angry with him, but trust me talking will help because it gives you closure. And you don't have to talk all the time. I mean just have one long honest conversation with him about what he did, why he did it, how you feel now, and how it made you feel when he did what he did. This does a great deal for you and helps you forgive him and move past it. Forgiving doesn't mean being friends, it just means letting it go and moving forward with your life. Trust me, it helps.
