WHOA. There is common welfare, and group "peace" matter - but that does NOT mean that anyone is responsible for anyone else's choice to drink. Period, full stop. That's not what common welfare is responsible for or means.
I have been troubled by people at meetings; one time a gentleman came in the middle of a meeting, screaming and cursing. He's a known problem and I believe has been put on "temporary ban" (at the big clubhouse I go to, there are temporary, ie 6mo, and permanent - a list is posted on the wall where announcements go). Another time, a man showed up and sat next to me, clearly drunk and smelling and near passing out. In both situations, I had to take it back to step one- I am powerless over alcohol - I am also powerless over others.
Sometimes, an AA meeting/clubhouse is the only safe place someone can go without fear of being arrested, etc. There is a line for balancing that sanctity being offered and someone abusing it.
My suggestion, too, is that you focus on you. You can be a friend in spirit, and separate yourself from her behavior and situations. That is ok and still supportive. I'd also....stay away from what sounds like drama and gossip. Truly- not your circus, not your monkeys.
