A friend who's on and off with her fiancé every month.
That's fine, but he's been violent towards her more than once now and is also incredibly verbally abusive and threatening.
He's told her he wishes he could smash her head in.
I've advised her several times to change the locks, go to the police, report him, speak to women's refuge, whatever it takes.
Once again he's come back and apologised and they've 'sorted it out' until next time.
I don't see any positives in their relationship as it is, there seems to be so much conflict.
I was in an abusive relationship myself 10 years ago and I know it's not always easy to leave. People will say 'just keep being there for her'. But I could tell her 1000 times to leave and go to the police, they'll still end up back together.
I understand it's not easy, but at this point there's nothing whatsoever I can say or do. I just don't know what to do anymore. She messages about him all the time, she knows very well what I think of him.
