I've been NC with my mum and two of my brothers for 3 years, every year on my birthday and at Christmas I get a message from them... Merry Christmas, happy birthday have a lovely time. I've never blocked their numbers because my mum is elderly and in poor health and as much as I really don't like the woman I would still want to to be informed when her time comes for if nothing else so that I can close a long hurtful chapter. Aibu to ignore the messages?
