Words of wisdom & advice:
Get to an al anon meeting. Educate yourself on alcoholism and addiction. Buy "Codependent No More." Detach with love.
None of our alcoholics are "just alcoholics." Alcoholics/Addicts can be charming, kind, loving, wonderful, intelligent people. Their disease does not independently define them, however, it does overshadow a lot of those good traits.
The only thing you can do is, take care of yourself. Lead by example.
