Enjoy your trip with your girls. Getting a change of scenery will be good.
I hope your D12 will consider therapy. She does sound like she is having a tough time. Maybe one day your H will wake up enough to realize WHY she is so upset at him. They truly are in a fog, aren't they?
Glad to see he re-friended you on FB.:) My H blocked me almost a year ago and hasn't used FB since. So very strange.
