Juju...I agree with Rick. There is no telling what's actually going on in his head. I have often described my H as a caged animal trying to escape when he first started pursuing D. It couldn't happen fast enough for him, and he was brutal and cold. Yet, when it came down to the bitter end, I signed the papers and he backed down. My D should have been finalized five months ago.
You are not going to be able to make sense of his behavior right now, so try not to give him the space in your head. You are an amazingly sweet person, and as JksD pointed out, his actions are about himself--not you.
