I still have some hope, since she seems prepared to accept help at the moment, but like you, I am taking some steps to prepare for the worst. It sounds like your AW is quite a ways beyond mine in the progression.
I will probably stick with Alanon just a bit longer to give it a chance. I like this board also, it lets me move at my own pace, and I don't have to interact with others in person. On the other hand, I think that to some degree, the alcoholic in my life has made me apprehensive of trusting and being around other people, and I want to conquer that. I don't know how long I will stick with it, but as annoying as it is, I think it would be easy for me to spiral into depression, and i did feel better afterward, better than if I had just stayed home and done nothing.
