Oh, I was thinking about this today and I still couldn't figure out why your H would avoid your S. But Nugget's suggestion makes sense. Course, the quetion becomes how big of a jerk are you when you start hurting the kids to get to the spouse if that's in fact what's going on?
Anyway, FL sounds like fun and I'm impressed that you think you will be able to go and put this behind you for the trip. That seems like the right thing to do, both for you and for your S. Have a great time.
