Dp and ex split when dsd was just over a month old. Ex has been high conflict over everything. I was not ow, ex initiated the split.
The court said that dsd needs a consistent story about the break up and her family. Dp and ex were to sit with a mediator and discuss what she should be told. Ex decided that she would tell her own version without any input from anyone, which was that mummy and daddy were very happy but then daddy met bandia and left. This is not true.
Over the last few months, dsd has been try to assess the story - asking me how old she was when I met her (nearly 3), asking how old she was when I met her daddy (8 months), do I remember her first words, steps etc. I've answered honestly while trying not to overtly point out that her mother is lying.
Last week, dsd seems to have decided that her mums version is the correct one, and spent almost all of her time with us saying that dp and I should split up so that her parents can get married. Daddy can live with them and it will be like it was before. It was the happiest time in their lives, daddy and mummy are not happy now, and they need to be a family again. Mummy's boyfriend can find someone else, but I shouldn't because she might want to have sleepovers with me.
She's a very confused child, and I don't feel that the story she's been told helps. She has no memory of them living together, so I'm not convinced this is dsds words. I'm also not happy with being cast as the ow when it's not true, but that's on a personal level.
We don't know how to help dsd, and we can't understand why her mum would tell her the story she did. We're not going to lie to her to go along with mum's story, but we don't want to add any more confusion either.
Any advice?
