I have found my anger has faded significantly since he's been living elsewhere. GiveLove's got some great venting suggestions. It's a matter of taste, but I sometimes listen to extremely loud, heavy music while driving on the highway (yay, SlipKnot!).
I also read an affirmation recently that suggested loving every emotion one experiences instead of trying to block it. Acknowledge it, but let it flow through you instead of allowing it to fester within. You have every right to be angry, but don't let it destroy you.
