What does your therapist say about whether or not you have commitment issues?

Maybe there are differences of opinion about what is or is not “abusive”. But in my mind someone who is overpowering in conversation, explosive, angry, and unwilling to get help is not a promising candidate for a long-term relationship and parenthood. You don’t want to be his therapist, but it sounds like the bulk of shaping his behavior falls on you and presumably will continue to do so.
