DD is 4. I left her father when she was 18 months, due to his emotional abuse of me. A large part of the abuse was trying to drive a wedge between DD and me, eg. physically preventing me from holding her. There is a court order. I'm the resident parent, her father has quite a lot of contact (every second weekend, every Sunday night, during the day Mon and Fri).
Ex has a history of badmouthing me to DD. I didn't realize how bad it had got. Last night she made a little speech to my parents which was clearly put in her mouth by her father: "I love Daddy not Mummy. Mummy is bad. She doesn't look after me properly. She took me away from Daddy when I was in his arms. [I left with her without telling him to go to a refuge.] She doesn't feed me properly" [We had just come back from ballet and swimming and she had cleared a plateful of healthy food].
I didn't want to make a big deal out of it, because I don't want her to feel guilty and confused. My parents were very upset, but of course we all cuddled her and told her we all loved her, and I think she felt better afterwards.
I told ex this morning very calmly that it's not good to talk like this. He started saying that it's true and DD is afraid of me [total nonsense, we have a very happy and cuddly relationship].
I don't know if there is anything I can do about it. I don't think I can stop contact, as I don't believe that a court would see this as damaging enough to justify ending contact. Ex has also falsely claimed in the past that I've been frustrating contact, and he'd love the opportunity to try to get the court to change residence to him.
Ex seems intent on reliving out his own childhood, where his parents fought a very damaging battle over him. I genuinely think he doesn't see or doesn't care about harm to DD, once he "wins".
Sorry for essay. Advice welcome.
