Random curiosity

[Waasitwroong]

I'm some time out of an abusive relationship and one thing that still confuses me regarding my ex, is that his mum took his older and younger sibling to live with her following the separation and left the middle with dad. This strikes me as odd and my gut is that he was abusive or inappropriate towards his sister (they don't really have much of a relationship). Can anyone give me any other genuine reasons as to why you would split siblings up rather than keep them together?

Any ideas?

Maybe his mum didn't like him. Maybe his dad insisted, or he wanted to live with his dad. Could have been which school he was at. Could be any number of reasons.

I have a friend who when she split from her ex asked her kids where they would rather be. Two chose to be with their dad, one with her.

Maybe he was the scapegoat in the family and his behaviour as an adult was caused by his traumatic childhood?

I do think it is possible his mum didn't like him as they still have a very superficial relationship. Definitely not school as he would have been at the same one as one of his siblings at all times.

I don't believe it was choice, as he did mention one time that there wasn't room for him at his mum's.

Possible, he did mention once that he was a loner and not the same as his siblings but I think that was probably just to garner sympathy.

Or it could be because he's always felt rejected by his mother, and becoming a loner was his way of dealing with the trauma of it.
