I went through this feeling as well. I broke off for a while pre-House of Wolves and will be doing so again shortly. It does feel like a relief to have it out of your life for periods of time. You know your own strength of will better than anybody on this forum does. I would suggest taking a break, don't play, stay off the boards. It doesn't mean you can't come back in a month or two and re-experience the parts of the game you enjoyed. That's where the strength of will comes in though, if you can't do that without getting completely 8 hours a day back into it, then maybe you should move on (and stay away from loot driven games entirely).
