I'm really not feeling hostile. And no, I'm NOT justifying his behavior, just trying to point out why he may have been justified in FEELING aggravated with you (NOT justified in acting on it in that way).
What I really see here is the two of you locked in a downward spiral of negative action/reaction, and you really need to break the cycle - and you can only do that by changing what YOU control, which is YOUR behavior. Reread DR and please read the Chapman book - I think you'll see a lot there.
