For long-term sobriety, he'll want to quit the beer for HIM, not just to get you. Recovered alcoholics don't drink because they don't want the stuff spoiling their lives anymore. I hear them say things like: "no alcohol, never again, under any conditions, for any reason". It's a promise they make to themselves.
If he wants to get beer out of his life, then he'll do it with you or without you.
If he's hurting, confused, wanting his family back, and getting all those emotions rapped up with the new desire to be beer-free, then the future is more unpredictable.
Just my 2 cents.
