Just a few questions before I make any suggestions...
When's the last time you went to a meeting?
How many different groups are there to choose from in your area?
I will throw out there that there were some "non-believers" in the group I went to and no one in the group was disrespectful of that. The group I liked the best seemed to be a good mix of traditional AAers and secular people, and they got along very well, and everyone's main focus was sobriety. They HP-geared people shared their stories referencing God; the others did not. It didn't seem to be a big deal, really. That's why I ask about the variety of groups in your area and how long it's been since you attended a meeting. Perhaps things have changed since the last time you set foot in one of their rooms?
There's no harm done in just going and listening, too.
