Anything she says now is completely unreasonable sounding to you. I can easily see how that can happen, given about 95% of the stuff she does say is wacky. But you are so tangled up in it, you are hearing some stuff that could be heard a different way.
You did go ahead and take those snow days off without talking to her? Why is that?
Here is the Parrot again: Get a more reasonable parenting plan solidified. Not a "you can take her anytime you want during the week" More like give her one or two nights a week, solid. more consistency for D, more consistency for her, and maybe she will calm the heck down. Nothing wishy washy, nothing questionable. It will cut down on need for communication. Get something very very formal.
