Will he be going to AA? If so, it might be good for you to go to a couple of meetings on your own, just to learn what the program involves.
Regardless of his own program/recovery, it's important to let HIM manage it. I respectfully disagree that you should "remind" him of how important it is to go to meetings--though it is good to understand that if he spends a lot of time at meetings or with AA friends, that's an important part of his recovery.
Getting involved in Al-Anon can help YOU keep your focus where it belongs--on yourself and your own recovery.
It's also helpful to understand that everything doesn't change all at once, just because your alcoholic has gotten sober. It takes time to unlearn a lot of the poor coping patterns most alcoholics adopt while they are still drinking. And it takes US time to adjust to the differences at home. Al-Anon can help you a lot with that.
