Hi,
I second the thought to go to Al-anon and also read Codependency No More...
I miss my axbf so much sometimes, I thought we were meant to be together too. But everytime a problem would come up, he would be drinking. He drank a lot at home by himself and with friends. There is nothing you can do about it. Maybe he is a wonderful man but he's also an alcoholic and until he decides he needs help all of the begging, pleading and worrying you do will not make a difference. As long as he is drinking the meds will not really help him.
My thoughts are with you....
