That's awful.
Most of the bad things in my case involved actual family members - grandparents, uncles, that sort of thing. I don't have any contact with them anymore, not that I ever had much.
I suspect that my ex is guilty of a lot more stuff than I've shared previously, but I'd better not talk about it openly.
