Whe he has drank way too much he is falling all over the place making a mess, making a scene, sleeping on the curb, and looking like a fool. I hate it!
Have you asked yourself if this is what you want? Doesn't sound like a very happy relationship. There's nothing you can do or say that will affect his drinking. It helps to understand that alcoholism is a progressive disease and his drinking will increase over time. "Powerless over alcohol": What it means is once an alcoholic picks up a drink they have no control over how much they drink and what happens. I'm a recovering alcoholic (21 years) and didn't start off as a falling down drunk either. By the time I got sober I was drinking two bottles of wine per day. A long-term friend said it was like I got in the elevator and pushed the down button.
I don't know you but I'm certain you can do much, much better.
