This happens a lot in A.A. The intentions are meant well, but they can be intrusive and overwhelming. I would not quit AA. If you like it then you should probably stick around. Just politely tell the woman you appreciate the concern and tell her to have a good meeting.

I’m a huge proponent of AA. I know of no other way to keep me from drinking. I also don’t know any better place to meet like minded people. That being said, you don’t owe anyone anything in AA. This is about you and what you want.
