I think that it's possible to take a little bit from different programs and make one that works for you, take what you like and leave the rest. I see lot of that in my RAH. He doesn't go to AA, doesn't like or agree with a lot of it, but I see him putting into practice some of the concepts.
The same goes for me, I haven't dived into Al Anon head first(I do attend meetings) because it just doesn't all work for me, but I do get a lot out of it.
We are both doing much much better then we were a year ago, both as individuals and as a couple.
