On the ‘Xmas with the kids’ thing.
The little ones really are too young to notice who’s there or not. Your older ones will likely see it as a bonus. As long as there’s a bit of Santa magic, a present and some nice food they’ll have a perfectly lovely day.
And they’ll get the very best gift of all- a confident strong mum, who doesn’t spend the day with those worry wrinkles permanently stuck on her face. A mum who knows in her heart that 2019 will be different, the start of a calm life where she (and they) can look forward to things safely, without that weight of dread of ‘what could he do next’.
In a way, it’s lucky that this has all come to a dramatic end at Christmas. It will make a big statement to him, his family, and everyone else that he has excluded himself from family time. He, by his actions, has put himself on the outer. He has closed himself off from this family, forever. He made his choice, now he lives with it. Nothing whatsoever to do with you. Put it back on him, in your head.
You keep your head held high, channel someone cold and strong and dignified. Then cozy in with your lovely family, who adores you, and feel the love. If he invades your thoughts, or comes knocking, let this be your mantra:
I WILL STAND FOR NO SHENANIGANS.
