I just recently stopped worrying...thinking aboutit etc...
I think I was able to do so when I learned that I can't expect the A to act as if he is not an A.
Also that I cannot get in the way of letting him hit bottom.
These things helped me because instead of wondering if he was drinking I just told myself he was.
And instead of worrying if he would get too drunk, hurt himself, etc. I just told myself if he does maybe that will help him.
Now I know longer worry and focus my energy elswhere. It feels great!
