Welcome to SR, Snickers3. May you find plenty of support here.
Yes, the great obsession of every alcoholic is that we can someday, somehow control our drinking again. What the alcoholic needs to not only realise but also accept is that alcoholism is a progressive disease. We may have been able to control our drinking before we crossed that line into alcoholic drinking, but now we can't. Your husband has to accept this for himself; no one can force him to see this. In the meantime, get all the support you can and take care of yourself.
