I was in an abusive relationship. As he wasn't physically abusive I didn't realise until an HCP pointed it out to me and put me in touch with Women's Aid. Since then I've realised quite how bad things were and that he ticks all the boxes for NPD. We have DC so I can't sever ties with him.
He's in a different relationship now. They also now have a child. I don't feel that he's changed much. He seems to be slightly more involved with this DC but it wouldn't take much. I suspect his partner is putting up with the kind of behaviour I suffered. She seems nice. I feel sorry for her. I was very isolated when I was with him and I didn't realise I was suffering in a way thousands of other women suffer. Almost no one knew about his behaviour and I'm so thankful that someone spotted it and understood what I was going through and tried to help me out.
I'm wondering if I should say something to his partner. I know it's none of my business but there is a child there who is the sibling of my DC. I want her to know she doesn't have to put up with his selfishness, gaslighting, manipulation and verbal abuse and threats.
Should I say something? If so, what? I don't want her to get defensive and upset.
