Yes, Alanon was helpful to me in getting me out of the house, and away from my alcoholic boyfriend's scary, self-destructive behavior.
I found the literature helpful; there is was in black and white - all the broken, sick dynamics that I had fallen into with my A. I was clearly co-dependent, and at least to an extent, enabling his alcoholism by my own denial and complicity. The people were warm and understanding, and it was wonderful to come out of isolation and back to a room full of sober people.
Sorry for what brings you here looking for help, but I am glad you found us.
