I think it's great he wants to be involved with the kids and their activities. Would it be possible for him to take the kids to their things without you having to see him? If not, then just a "hi" and go be somewhere else? I don't really have an answer for you. My H will come to one or two of D13's shows a year, but otherwise does not see her practice. If he happens to pick her up (which he will next week) that's about it. He decided to move about 60 miles from here, so he sees them on Sundays and I am not here. I'm sure you'll get some ideas from others here that may be more helpful with this.
As far as an outlet goes, I really don't think your kids stuff fills that bill. If you didn't have any conciderations besides what you want, what kind of outlet would work for you?
