welcome to the forum rednails.
Unfortunately there are very many "functional" alcoholic type people. And there are those who are either in denial of their own problem or or actually unaware of it.
It would be nice if you could get your husband aboard and try to do this as a team.
But if he isn't ready, there is nothing you can do except lead by example.
Perhaps get yourself some literature about "alcoholism". There is plenty on the web.
If you are convinced that you yourself need to quit, you will find plenty of resources and get plenty of support here.
