You can't get him to stop drinking, that has to come from
him. Until he wants to get sober, you are wasting your time and your voice trying to persuade him.
Alcoholism never gets better on its own, it only gets worse. Do you really want to spend your life fighting with him over his drinking? He values drinking more than he values you, which is very sad and frustrating.
I'd think long and hard about how you want to spend your life.
