I think if I had all these resentments about my partner's AA attendance, I would work on trying to accept that this is what he's doing right now to save his life. 10 months sober is very new in sobriety and he probably needs those meetings and the guidance of his sponsor.
Does he want children? I mean, you are pregnant and he is going to do what he feels he needs to do to stay sober. That's what you'll have to come to terms with...
