DP and his ex had an incredibly acrimonious breakup. He had to go to court as she stopped all contact - claiming ridiculous safeguarding issues (he bought his two year old a fake poo bath toy to make her laugh - apparently this was a reason to stop contact). All was discredited. She assaulted him, all caught on CCTV. The police eventually dropped it after she refused to accept a caution, saying too much time had passed!
She's now started telling her 3 year old that my 13 year old is 'mean' and messaging DP to say that teenage dd used the word 'crap' in the presence of her 8 year old child and this is unacceptable. Dd is normal. Great school reports, never ever had a detention or a negative behaviour incident. Not perfect, but she is great with DPs kids. I feel angry that she's being dragged into the dispute here and I worry that she is trying to alienate my dd from her step siblings. I think step kids are interrogated when they get home. Dd has also been ignored when she has seen DPs ex out with the step kids after school. Step kids have tried to say hi and literally been dragged away.
AIBU to be furious?
