Poor Little. It sounds like he has some SERIOUS issues. You are better off without him even if he is the smartest, funniest, sexiest guy in the world. He sounds like a serial cheater in a major way and it doesn't seem like he is going to change any time soon.
I would not be at all surprised if he comes crawling back to you, but he sounds like bad news. Of course you know him best so you would have to make that decision when it came to it. But he doesn't sound like he made an accidental mistake, it seems like a pattern.
Obviously he made a HUGE MISTAKE in leaving you, but maybe it is for the best for you. At least right now you need to focus on yourself, curl up in a ball and cry or whatever you need to do to take care of yourself.
