Is her sponser a man? Have you heard the infamous line " I love you, but I am not in love with you" yet?
I hope she does need some space. But AA "can be" a cesspool of deliquents that prey on the vulnerable addict in the early stages of recovery. This is by no means an indictment of all AA groups or members. The program works, if the addict works the program.
But often addicts seek out out those who enable their addictions......they form bonds with those with similar problems. They mirror each other feelings, and its easy to blame your spouse, parents, whoever.... for your problems.
I hope this is not the case with your wife......I would not even challenge her on this topic............... But I would be observant.
