Coming from in recovery functioning alcoholic and he drinks 6 or more drinks a day that a serious issue.

Does he ever get aggressive/ controlling with you?

Tapering at first worked then I found I just drank 75% more on weekends then weekdays. So I went cold turkey multiple times and found that my situations even though I was a social drinker at first to get rid of the awkwardness and anxiety! When I was drinking all the time!

Maybe ask him to see a addictions counsellor or something like that mine really helps me!
