I am already thankful for finding this site and for everyone's good wishes.
I have discovered an organization called Moderation.org which might be a better first step for Kevin and I than Al-Anon. At least it is a place for ME to start.
In regards to my mother, I saw her drink moderately and contain herself for eight to ten months at a stretch -- then she would binge and it would get bad. If I could have that with Kevin (instead of the every four to six week binge), I would be very, very happy.
Again, thank you all!
