Your husband is an addict and is choosing to drink. He doesn't seem to have a problem with all his medical issues, like you do. I understand that you love him, but love does not cure alcoholism.
I would keep hitting alanon meetings, try open AA meetings and read all over this forum. One day either you or he will understand that this disease is progressive and only gets worse. I wasted 34 years of my life praying my axh would figure that out, it never happened for me. I have been free now for 2 1/2 years. It was the best thing I have ever done, for me.
Hugs my friend, there is nothing worse then watching someone you love slowly kill themselves.
