Welcome to the board.

Have you or your husband been to AA?

It sounds like you both need to go.
If he is addicted to alcohol then you probably play a part in enabling that.
So what changes can be made there?

Most of us here are enablers, so welcome to the club.
It might not always be for alcohol but it might be some other addictive behavior.

What does your husband think about getting divorced?
