It does not matter what's wrong with him, you need to get out, and you need to get out now.
Please listen to me: You are at risk of being hurt or worse. This is not about something being wrong with somebody, it is about your safety. This behavior could have many different causes, but that's not relevant to your situation.
Call 1−800−799−7233. That's the National Domestic Abuse Hotline. Speak to the counselors there. You do not have to press charges if you don't want to, but you do need to get out for your own safety. Please call; you are at risk.
