No living family.
My partner failed to tell me about which days he has his DC over Christmas despite me asking repeatedly since October, and their mum being an amicable co-parent who likes to plan ahead.
So I couldn't make a plan for an adult friend Christmas dinner party, as I usually would, in case the young DC were there, and couldn't plan for DC because I didn't know when they'd be here. I've bought DC and him a bunch of presents, he's bought nothing as he's hugely in debt and been unemployed for over a year.
On the 22nd, still not knowing, I asked for clarification, to which he got angry and escalated everything, pushed me into a wall, stormed out and stayed out overnight, and then finally, after much texting from me, said that he's now in a city 2 hours drive away with his DC at his brother's.
So I'm completely alone at Christmas, in a lot of pain because being pushed into a wall fucked up an old back injury, and now single because I sure as hell am not putting up with that behaviour.
We've lived together 2 years and been together 4.
