I'm having the same problem here. After a weekend of her hanging out with the 'family' on my first weekend with the kids in 2 months, just to find out she didn't want to spend the weekend alone; I had to put my anger aside and realize that the kids need to be taken into account, this is a kid holiday anyway. i needed to do whatever it took to make sure that the kids trick or treat with their friends, in their neighborhood. I extended the offer to the W to come over and take them out while I stayed back and handed out candy since it was her time with the kids. I at first was going to just have her pick them up after they were done, but figured this was the better approach for all.
