My only sugestion is to live and let live. I know it's hard especially when he keeps playing this passive agressive game to make sure you "see" his anger/pain, but if you you can get him to realize that the passive agressive BS doesn't phase you, it will probably stop. And if he is a true friend, then it should blow over enough that you can talk about it in a reasonable manner and move on with your lives, hopefully still as friends. I've been through this a million times with my best friend in different ways, but somehow our friendship has always survived. But you are right, the passive agressive BS is the first thing you need to work on getting rid of, and that is usually as simple as not reacting to it in any way until it stops.
