Now, I only go to NA. I feel comfortable there.
When I first got clean, I attended whatever 12 step meetings were available at the time I was available. In the area where I live, I don't like the AA meetings, but that's my choice and opinion of them. I've been to AA meetings in other states and cities, and they were fine, I liked them.
It's just a matter of perspective. It's should be a matter of what feels comfortable to your husband, where does he feel he fits, and feels safe. This shouldn't be for anyone else to determine but him.
