Sorry, forgot to comment on the other post... don't read into it 2TP. Again, it's just logistical. She's leaving you with the kids, she should let you know. If you want to read anything into it, take it that she doesn't dislike or despise you so much that she won't even communicate the most basic of parental responsibilities.
I have been there btw. After my W caught me spying on her FB account the next week and half was horrible in our house. She was so angry with me she could barely look at me or talk to me. She literally would not have told me she was running to the store. She would've told the kids and then when I wondered where she was they would fill me in. We're past that condition now, but it was terrible. So yes... it can be even more frigid and cold in your house.
