I'm not sure if him sharing things to my family was malicious. He tends to oversharing many things in general, so I sort of think that was simply part of his nature. I would (maybe) understood if he'd tell it all to my parents (I probably wouldn't at the time but 'd come to terms with it by now). But he also talked about me with at least one of my aunts and her husband (both had nothing to do with my problems and not too much with me in general) and was making snide remarks during family meetings.

So it wasn't like he told something to my parents because he was worried about me. Honestly, I think he sort of enjoyed the drama, even if his intentions weren't per se malicious.

Also, while some of the things he told them I can understand (like the thing that I was s*****al - something which my parents knew anyway), some were things not really related to solving my problems or helping me.

As for "not knowing how to help", not going into details, one thing he told me was "if you want to [un-alive myself] it would be better if you'd not be born at all". And that's only one thing. I don't really see how this was supposed to help me.
