DB divorced 10 years ago. I haven't seen ex wife since before then but regularly see DB, niece (aged 18) and nephew (19). ex is unstable, and manipulates my niece telling her she's going to kill herself, not letting her move out to go to uni, won't her learn drive, basically clinging on to her emotionally. DB gets furious about this which puts my niece in a horrible position, feeling whatever she does, placate her mum or resist, to please her dad, will end badly for her. huge emotional burden for her with both parents behaving appallingly. I have tried to explain this to DB but he can't take it on board. I just want to help her, or find her the best help I can. I have suggested she talks to college counsellors, but I don't think she will. I've offered to go with her somewhere but I think she knows her mum will find out and make life hell for her. She says she loves her mum very much but can't bear to be her emotional support any more.
