I know JUST what you mean. I think for me it was a relief too..sadly it validated what I knew all along. I still know it. However...it has finally pushed me to the point of realization of alot of things, mainly that I am in charge of me. If he continues to drink that is his actions, not mine. He will have to live with the fallout of that as he is now realizing. We are all responsible for our own selves and our own actions. I cannot control if he drinks, but I can sure control how I react and I have actively done that. It has helped me to feel much more in control of my own life.
Good Luck and God Bless!
