Admittedly I only read about half of what you wrote (sorry), but I think I get the main jist of it: you're unhappy with him because of some definite issues he has and are conflicted on leaving him or not. He frankly sounds like a spoiled child. I definitely don't blame you for wanting to leave. All of what I read are pretty big issues and will only lead to you being miserable in a marriage if not divorced later.

If he was willing to work on those issues, would you still want to be with him? If you can answer "yes" to that, it might be worth trying to get him to go to couple's counseling with you. If he can't manage it or gets worse, get out of there. If you answered "no" or similar to that question, I'd trust that feeling and break it off.
