While I don't agree with being strong-armed into doing anything (try merely unplugging the phone for a day!), I truly hope that you can take away some beauty from Christmas. Focusing on your daughters is a great idea. Maybe arrive with a tradition, such as a reading or prayer or a food item/drink preparation that you can share with them alone - without any necessary involvement of Andy.
Regardless, Merry Christmas to you and yours! I hope this new year brings you both peace and happiness.
Isaiah enjoyed DD4's drawing you send - its on my computer desktop. Thank you!
