My DS is 45 and since his marriage of 15 years broke down (his wife cheated and he couldn’t forgive her) he has been dating an array of women under age 30. He has been in a relationship with a 28 year old woman for the past 2 years; she is disliked by quite a few family members as she is not the type of woman we have ever seen him with. We all used to spent Christmas, New Year, birthdays, holidays and lots of family get togethers. Now it’s just drama every time we try to arrange something because the first question most ask is ‘Is she coming?’. I don’t particularly like this woman but want to keep a relationship with my son, but it’s really causing a massive problem within the family. We are all supposed to be meeting in London next week, 20 family members coming from all over the UK but tonight they are dropping like flies as they realise she is coming. Many are arranging to meet still despite the event being ‘cancelled’ in the family group chat. They are have started a new group chat but not added my son and are suggesting I go but not to mention it to my son. I would love to see my siblings but as we don’t see each other often, but feel I am betraying my son. AIBU if I meet up with them all without my son, his family and girlfriend knowing? My son is aware of how some of us feel about his girlfriend.
