Her boyfriend is extremely paranoid, and tries to commit suicide (he says). He's hurt her twice by accident because he doesn't realise his strength (I'm weirdly inclined to believe that he hasn't done it on purpose those times).
He's obviously ill at best and a abusive psycho at worst. I've told her to leave him, she says she won't in case he hurts himself. I think she's scared to be alone too.
How can I open her eyes to how dangerous a relationship with this man is?
