My family is falling apart.
A) My oldest brother walked out on his wife of 30 plus years for a girl 2 years older than his own daughter.
B) My sister has been divorcing her husband for 5 years. I'm not even sure why it is taking so long. They can't be in a room with each other for more than 5 minutes before she starts screaming at him. She has lived with our parents for the past 7 years, but now she has a new boyfriend.
They both want to bring them to my house for Christmas. I don't want either to come because
A) SIL is more like a sister to me, she has no other family left and as far as I am concerned she is spending Christmas with me.
B) I have looked after my sister's son for the past 8 years. He doesn't want the new boyfriend there and if he deserves one day to be good, it's Christmas.
I told them both it wasn't on, they aren't talking to me (but still want to come) and have pulled our parents into it. My parents told me it was none of my business who my brother and sister brought with them!
