My mum is a narc.

I have a big family and last Xmas my family were going to visit a few days after Xmas as they had plans. My mum demanded I’d be there on Xmas day and the day everyone was coming and didn’t like that I would see my husbands family. I said we would come when everyone else does. She has just asked me about this year and said because I abandoned her last year she’s going away. I asked will there be a gathering a few days after Xmas when she’s back to see everyone and she’s just ignoring me now. It’s so odd. What would you do? (She isn’t someone you can just talk to her about things as she gaslights me)
