My ds is 18. Earlier this year my mum cut me out of her life after I asked her to stop saying something nasty to myself and my sibings. She has fallen out with everyone over the years and I was the last person still putting up with her. She went absolutely nuts at being challenged and and hasn't spoken to me since. My ds and dp have known all along and are supportive but my ds is sad now as he really expected her to change her mind and he is concerned about xmas as he won't see my step brother or step dad and he usually sees them every year. This year will just be the 3 of us and my sister and her partner. I feel bad for him and don't know what to do!
