He wakes me up in the middle of the night constantly to talk, fight, ask a question, you name it. Then when I complain that it's the middle of the night he ridicules me asking why I can't sacrifice my sleep for him.
That's used as an interrogation technique with prisoners of war. Denying people sleep. It is a form of abuse.
I think the thing that worries me the most about your story is that he's said before that he's leaving, and then he doesn't. I think all of you could use some time apart right now, so that you can get sleep, calm down, and most of all, so that your daughter doesn't get put in the middle of the dysfunction.
