Dan, I have to respectfully disagree with the recent advice about "her clutter". You have on-going legal proceedings and you are both living with your children. I would not move anything at this point. At least wait until after your first hearing and you see how things are going to go.
Besides, the legal aspect, packing things up would be much more disruptive for your kids, who so far have seen you acting with grace, integrity and strength. They may see the packing as retaliation or a threat to their security. While moving may ultimatly be in the cards, you don't want them to worry unnecessairly.
You have been doing great recently with the GAL, 180's and detachment. Just keep that going.
By the way, for the vacation, your kids are old enough to help you with the chores. Let them help decide the meals, go shopping, even help cook. Give them clean up jobs each day. They'll think it's fun and it's an ego boost for them that Dad thinks they're old enough. Just be sure to frame it that way.
