I could really do with some advice here. I divorced my husband very amiably in 2010. We shared custody of our only child, she was 14, and we had a great relationship. No other person was involved. He started to date again and I would give him advice if he asked otherwise we lived our own lives. 4 years ago he started dating this woman who then moved house so she could be near him even though he wasnt that keen. Within a year I had a meeting with him where he told me he could not speak to me or see me any more. Naturally I was hurt but I let him go because what right did I have to interfere-clearly this new woman felt threatened even though we had been divorced for years. Since then she has never once let my husband visit my daughter who is at university doing her extended degrees etc, alone. Every visit she is there. This week my daughter went to visit him for the first time since lockdown ended. She stayed at his house, which has kept and uses a couple of times a week as he has refused to move in with this woman. Every day this girlfriend has been round until yesterday when she decided she was staying the night and days until my daughter leaves-which is tomorrow. My daughter is beside herself. She just want to be with her dad and he stands by and allows this woman to take over. She even brought her two girls round to his house even though my daughter had said to her dad she was not ready to meet them. My daughter rang me today begging to come and stay with me when she leaves as she is so upset about how this woman is treating her dad. Apparently she talks to him like crap and bosses him about. The man I was with for 25 years has changed completely. He was a strong, kind, selfless man who was a lovely husband and father. The things he is doing are so out of character. I am worried about him but helpless as we no longer speak. Please could someone advise me on how I advise my daughter on the way forward. All I want is for her to be able to have a good relationship with her dad but this woman seems intent on destroying that presumably so she can have him all to herself? Is she a narcissist? I need to be fair and just and not say anything to influence my daughter against her dad. I just want to do the right thing. Advice would be so helpful right now. Thanks
