BS16 and I are out doing some errands and he gets a text from his dad. Bs tells me that I have to hurry up because dad is coming to pick him up right now! This has happened a couple of times before, about 1x a month. we moved a few hours away from exH so now he just pops in and takes them to dinner whenever he's coming through town.  I have not gotten notice that he wants to take the kids out once, he just shows up and expects us to rearrange everything.  Another thing is that he won't come near our home.
