My mum has just called me to say that she's no longer coming to Christmas dinner at our house. We invited her, my sister and brother who both still live at home, my father and my uncle ( her brother) weeks ago and have bought the food in. I'm hurt she isn't going to spend it with me and her grandchildren. Background to this is complex but basically my dad was very abusive and violent throughout my childhood to my mother and to us. She divorced him when I was 5 but out of fear he remained with us for about seven more years . She eventually kicked him out when I was about 12 but he remained 'on the scene'. They still live separate and he spends a lot of months abroad in his home country but when he is here he goes round most weeks for Sunday dinner. I've always found this odd but my mum has a tendency to take in waifs and strays and feel sorry for people and she says she feels sorry for him being alone in a country with no family bothering with him (his fault for terrorising us as kids) She also has her 70 year old brother round for this weekly Sunday dinner as well. To add to the awkwardness of that her brother hates my dad but tolerates him through a Sunday dinner. I don't speak to my dad but I tolerated him last Christmas at my home so that my mum would come for Christmas dinner as she seems to harbour some sort of obligation to have my dad at Christmas. They are not romantically involved in any way although I know it sounds that way. When she rang she said that she couldn't come because my brother has decided to go to wales on his own instead (?!) and my uncle is refusing to have my dad in his car ( only my brother and uncle drive). I asked why she, my uncle and my sister couldn't come and leave my dad and she said she would feel too guilty. I can't believe that my mother is choosing her abusive ex partner that literally nobody else speaks to over her daughter and grandchildren plus the fact we've bought too much food now. I even said we could do dinner at 12 and she could do an evening meal with my dad later but that's been vetoed too. Generally my mum and I are very close, speak on the phone every single day and she visits twice a month ( we live about two hours away). Is it unreasonable to be angry about this?
