Hi S. I'd oppose it if my kids were with him, but it seems to do with what's possible. He's still drinking so he's not in recovery, 10 months is nothing with an active disease, and he has a history of putting the kids in danger.
What would be the consequences of you opposing? Fees? Bad feeling? I'm wondering why you have a question in your mind?
Remember that he's richly earned the need to check his sobriety.
