I’m trying to convince my daughter’s Dad to let our daughter spend Christmas Eve and Christmas morning with my more recent ex, and her stepsister? They’re 15/16 and really close. He thinks she should be with either him or me on Christmas Eve/morning magic of Christmas innit and is digging his heels in. I get that it matters to him, but I want the girls to have fun, it’s not really about us is it? The three of us will be having Christmas dinner at his house, stepsister invited but might not be able to. Maybe IABU maybe he is maybe neither?
