If she has stopped going to AA and is actively drinking, are you honestly that surprised that she is engaging in alcoholic behavior? i.e., manipulating you, lying, etc.
I agree with you that it's best to stick with people who are actively working their programs.
You have no control over her or anyone else's choices or behavior. But you do have control over who you chose to spend time with. I'm not saying completely ditch your friend. Offer support if she reaches out for help. But I know if I was in your situation, I'd cut social ties with an active alcoholic, at the very least as to not put my own sobriety at risk. No need to confront someone who is not thinking rationally because they are in active addiction.
