H and I are both recovering alcoholics. I have a ton of sober and not sober alcoholics in my life. I have been going to ala-non for 5 months and it has been instrumental towards learning to detach with love from my loved ones.
Honestly, it's become more important for me right now than my AA meetings.
As for your daughter, they are both adults and can certainly manage an R on their own. I wouldn't make any comments to let you know it bothers you. But answering "ask her" politely and kindly when he asks about her is a good thing to do. Puts the responsibility on him. I work really hard not to put guilt on my H. He is the one who is responsible for his R with our kids. He can see them anytime he wants.
