These are all excellent ideas, and I plan to act on each.
He won't be handing me any drinks, that's for sure! Since I've given up alcohol, it really shouldn't be an issue - since I drink water constantly.
I will make up an errand to get out if I need to. Chances are though, the kids are not going to let him corner me anywhere. Due to his behavior towards me, I've had to let them know at times - especially when someone had to come over and stay with me to make sure he stayed out.
I can excuse myself to my room, if needed. I really think he's going to be on his best behavior, though. He used to adore his children, and though he may be distant these days, I doubt that has changed much. I know the kids appreciated me inviting him. They were so happy I made the gesture. I plan to just enjoy my company, with one exception, and have a really good time. I hope I don't cry, though, with the ever present thought of "last Christmas together" running through my mind. I hope to stay so busy, I can't hear my own thoughts!
I plan to be on my best behavior. The kids are not going to see me acting in any way other than cheerful, relaxed, and happy. That is my plan.
*By the way - the youngest of my "kids" are 19! It's just this momma's heart that still sees them as youngsters. The adult children are truly aware of quite a bit that has occurred. I had to let them know, for my safety.
