Mending a broken heart?

I understand it is hard to trust when you have been hurt, but don't let some loser who ruined his relationship with you ruin any future relationships you may have with others. You should be wise to a bad guy now you have been with one before so you should know what to look out for. Sounds to me like you're doing the right thing by getting to know him first and as you said you havent slept with him. Don't think about the past too much because it will only ruin your future. Good luck with the new guy, life is just trial and error. Make sure you don't rebound and hurt someone because if you're not over your ex it is a bad idea to get involved, you may not even know you are doing it, but when you've been hurt you will love attention from any guy that makes you feel good so make sure your feelings are genuine.
