As the others said, it is for family of alcoholics regardless of whether they are active, sober or in recovery. And YES!
RAH was sober when we met, and for the first 8.5 years of marriage...then he relapsed & I was completely blindsided. I wish I would have understood the disease (I had no prior experience with an active alcoholic) and the support available to me as his spouse before that happened...I'd like to think that I could have avoided some of the pain that came with his relapse if I had been better "prepared" for the possibility.
Alcoholism is a disease...if your betrothed or spouse had diabetes, you would probably educate yourself on what that means & how to support them in dealing with it, and you would probably be healthier for doing so. AlAnon is our medicine...our treatment...why not make sure she knows its available to her and that she may find it helpful? And as lillamy said...it's a program that applies to all areas of our lives.
All the best to you & yours!
