Hiya
Sadly, there is nothing you can do until he 'want's help. My hubby was an alcoholic for 8 years being with me until he quit. I went through hell and left him on several occasions. It took him attacking me and his friend and me leaving him to realise he had to stop. He was verbally abusive while drunk and I don't know why I stayed with him but anyway, he quit and has been sober for around 6 years now. Had a few blips along the way but now he is sober.
I am sorry I don't have anything really helpful to say other than you can't help him until he wants help.
