Glad to hear you will be taking care of yourself over the holidays. I am beyond fortunate that I have never had to "split time". I gather lots of ideas from those that do, so when it's my turn...I'll have lots to fall back on.
It's so sad that he dosn't get he's really hurting the kids with his attempts to hurt you. Someitmes there is no coming back from that. I have an aquantiance that hasn't spoken to his mom in over 40 years behind that kind of thing. He isn't bitter or angry, just not intersted in any kind of R with her.
I hope that's not the case for your kids.
I'm starting to think about New Years eve and come up with a plan. I'm looking for somehting different. I'm sure I can make it a good one.
