My brother met his now wife 3 years ago. They moved in together after 6 months and married last month.
He has 2 children, my nephew and niece, from his previous marriage who are 16 and 14. He now also has a step son and step daughter who are 15 and 14 who don’t see their dad so live with their mum and my brother full time. My niece and nephew used to stay with their dad 3 nights a week but since his wife and kids moved in, they don’t see their dad as often and hardly ever stay over. His step children are very different to his children and they don’t really get on. My nephew was also expected to share a room with his step brother and my niece with his step sister which neither of them like doing.
Now that they’re married, my brother has said he expects us to treat all the children the same. When I asked what he meant by this he said that he wasn’t happy with us doing things with our niece and nephew and not including his step children. He also says that it’s obvious we spend more on our niece and nephew for birthdays and Xmas and that needs to be equal now.
I plan on taking my niece to a concert if we can get tickets and my brother says if I do that, I need to take his step daughter as well. I don’t want to and my niece doesn’t want her there either so has said she would rather not go. I also don’t think it’s right that we either have to spend more on my brothers step children or reduce the amount we spend on my niece and nephew at birthdays and Xmas.
We are kind to my brothers step children and we buy them gifts but obviously they’re not my niece and nephew and I don’t have the same relationship with them.
I’ve spoken to my niece and nephews mum and she says that they really value our relationship with us and are worried about things changing. They have told their mum that if their step siblings have to be included in things they do with us, then they would rather not do them.
My brothers step children are very different to my niece and nephew. They are very loud, misbehave at school and are in with a cool troublesome group at school. My nephew and niece are on the quieter side, do well at school and are very bookish so the total opposite really.
AIBU to tell my brother he can’t dictate my relationship with all of the children? How would you react?
