Ex and I divorced 3 years ago. We were together for 6 years and have 3 DC. We don't get on. He has DC 2 days a week.
My mother, with whom I have fraught relationship, continues to support and spend time with my ex. She claims this is in order to send time with the DC.
My brother and his wife along with my mother had Christmas with him and the children last year and all meet up for meals out every few months (along with DC).
This makes me feel uncomfortable. Ex has given me a lot of stress over the past few years and assaulted me during break up.
I have a partner of two years. He also finds this uncomfortable, especially as my mother and brother make no effort whatsoever with him.
