I don't think the question is "what is wrong with him?" rather "what is wrong with you?" I'm not trying to be rude, but what is your reason for putting up with a guy who treats you badly and uses you? Of course he sticks around because you support him financially. He lies, he cheats, he threatens you. Really, who cares what's wrong with him!? He's a hopeless loser. I think you should focus on healing your own issues, and start by kicking his butt to the curb.
