How would he find out about it? I would just go ahead and go, don't tell WAH about it. But also know that the other mom has a right to invite him, and he has a right to attend at that point. Even if he just finds out about it in passing, I think it would not work out for you to somehow try to fight his attendance. Just accept it as a possibility but don't go out of your way to notify him of it.
I see the problem with the group, though. It's not like you can just pick a new group of friends so easily. You have D7 most of the time, and that is where her friends are. But are there any efforts you could make to meet new, unrelated adult friends? What about your friends you felt like deserted you a few months ago? What's your R with them been like lately?
