Raisin, I just wanted to say that I'm sorry that you are hurting.
I think it hurts as badly whether an alcoholic or non alcoholic breaks an engagement. That is a huge disappointment for anyone and sounds like you were blindsided as well.
No, it had nothing to do with how supportive you were or were not. Was he a supportive partner to you?
Who knows who may come around the corner in 2011. Be ready!
