jaguar, welcome. To find out more about alcoholism, I read Under the Influence It really helped me identify the behaviours my XAH was demonstrating. It didnt stop them hurting, didn't make it 'better' but I better understood the disease and its progress. It helped me (along with Codependent No More) to make informed choices about how I wanted to live MY life.
Stick around and keep posting. This forum has supported and educated me so much - I hope you find the same benefits I have here!
