Glad you had a good weekend, and I agree. Letting him see you mad/upset just gives an evil emotional victory to him.
I have vowed, and have kept it for 5 days now that W will never get an angry or upset comment from me, period - sole exception being something that specifically hurts kids.
She is curious already, I can tell, and I'm loving every minute of it!
P.S. Tomorrow is our first Christmas not being together as a family. W let me keep kids Mon and Tue because they are normally her days - she said, "I know you'll be alone over Christmas, and it really stinks." So, I'm not saying a WORD to her, but I've let my kids know about the Christmas party I'm going to on Christmas Eve, and I'm sure they'll pass it on to her.
MUAHAHAHA!
I'm so proud of you that after his big old stupid trip, you deigned to honor him by saying basically two things. You go!
