I can totally see why it upset you, but I agree with Hammer: addicts use people and now that he's realized you're gone, it's time for him to move on, the sooner the better in his alcoholic mind.
It's been six months since I broke up with my ex, and I'm on SR all the time spouting all my silly advice, but just last night I went looking where I shouldn't. I saw my ex's new art work and was very bothered by the fact that one of the pieces is called "Freed Man." I don't know what it means but I imagined all sorts of things, and it hurt like h*ll. Just seeing his dumb work hurt me. Serves me right. I feel like a complete idiot today.
So, yes, close your account and don't go looking where you know all you will find is pain. (I am talking to myself as much as to you).
Happy Independence from Alcoholic's Toxic Behavior Day to us!!!
