Well... I don't know as I have much of anything to offer in the way of an answer to the question you posed in your title.
I don't know as I'd say I always hated my family. But I didn't
like them... & I got as far away from them as possible as soon as I could. I basically never went back. They're all long since dead now. And I still can't work up much in the way of fond memories for them.
Sometimes I wonder if it was more me than them. But I really don't know. I suppose there was probably plenty of blame to go around. Anyway... I would presume this is the sort of thing one would need to explore, in depth & over time, in therapy if one wanted to get to the bottom of it. I don't have any plans to do so.
