Yes, it TOTALLY [censored]. Just hope that OW is putting pressure on him and pouting about him not being with her on Christmas. In fact, maybe she gets pissed at him cuz he doesn't call her enough when he's with you and the kids!

In fact, for all you know they could be breaking up right this minute.

So suck it up - you don't want to break up over Xmas and have your kids always associate Xmas with their parent's breakup. I had to do something similar - but it was worth it.
