Oh geez. Family. So many weird dynamics. All the 'logic' seems to go out the window, I get that.
The gift giving: If you're too old to sit on Santa's lap, you're too old to send out, or request, any gifts. Good lord. But I do understand why you feel the way you do. Its a lose lose. I guess have the kids make them something next time. Truly, that's priceless....if they're able to see that. Otherwise, try to detach.
She kicked you guys out? That must have been a doosie. Obviously now isn't the time, but I'm guessing there are two sides to this coin. If it hasn't already been done, maybe a review of your side of this, and a followup amends, is in order? Only reason I say this is it might help you in the long run. Sometimes cleaning up my messes helps me detach, lose the guilt.
Its only a few hours. Hang in there.
