Well I have to say I am glad that you got out of that situation, it could have easily turned from bad to worse and I can tell you had trouble saying no at first and that took a lot of courage. Good for you. *hug*

My first impulse regarding facing him at the AA meeting, is that if it is at all possible, find a new group. I don't know how AA meetings are set up so I don't know if that' feasible but I think if it is, it would be the best thing, just to get away from this guy. After his behavior and him thinking that he can call you and expect you to still come over after your telling him no so many times, I'm afraid he's not going to let up unless you avoid having to face him altogether.

I don't know if this helps but Hope so.
