I spoke (informally... not an appointment) with a psychologist at the local health dept and he suggested Alanon as well as a place to start.
He said that many Alanon members have had to deal with living with an "active" alcoholic, an in my case I never knew my gilrfriend when she drank, but he felt Alanon would still be beneficial.
I posted the info about my Ex girlfriend being sober for 15 years... going to AA etc. That having been said, and the fact I never actually dealt with her actively drinking, do you folks agree that Alanon will still be beneficial for me? (I assume it will)
