I don't know him and I don't really know the history, but it sounds like the difference in the way men and women communicate, to some extent. He is trying to be conciliatory. I am not saying that you shouldn't leave him, but I don't see this as a particularly abusive or alcoholic-type interaction.
I think this sounds like typical male "I want to make up and I love you and I can show you by having sex with you" cluelessness.
jmo. He may be a raging abusive A most of the time, for all I know. I just don't find this all that strange.
