From what I can see, he's not really in recovery at all. He's continuing to drink, but trying to keep a lid on it so it doesn't get "out of hand." It's really up to you how long you want to put up with this.
There is no point in confronting him when you know he's been drinking (and deep down you DO know). Calling him out on it won't make anything better. His alcoholism will continue to progress, even if it seems to have plateaued for now.
What are you doing for yourself? Are you in Al-Anon? Have you talked with a lawyer to find out how you can protect yourself in the event it gets to the point where you have to leave?
