Re: I could Kill him when...
After being married for entirely too many years the best advice I can give you is to take a page from his book and not get too hung up on whatever it was that you were fighting about. I am sure that it affects him too, unless he's an insensitive jerk, and he's probably exhausted by the entire drama.
Sometimes the best thing to do after a fight is to leave the scene - go to the library, go shopping, take a nap, or read a book.
