Yesterday my partner looked on her DD phone (she's 10). Recently she had been speaking about new friends and had swapped numbers with them at school. Over the weekend she had been added to a class group chat that we were unaware about.
Anyway when looking through the phone it became apparent that my partners DD has been stirring up trouble between 2 girls and screenshoting the conversations she had been having and sending them to the other girl.
She then changed 1 girls name in her phone book to a mean name and sent that to another girl and was mocking her. She basically bullying.
We were both so angry. DP went to speak with her and told her off and the consequence was no phone for a long time as she is showing she's not mature enough or ready.
Her DD cries and admits it but after this she then goes onto say how she's a horrible person, doesn't want to live anymore etc.
She's done this many times before when told off. She's usually a happy girl, no issues. But when she's told off she resorts to this kind of stuff. Eg everyone hates me, I'm worthless, I don't love you.
My DP didn't see it to begin with but I pointed out the only time she says these things are when she's done wrong and called out on it. DP last night did say to her you can't say rhis stuff it's emotional manipulation. DP then comes to me and asks me to check her mental wellbeing is ok, I reassured she's fine but went in to check.
I was nice, explained people make mistakes etc. Asked why she thinks she's horrible. She couldn't give an answer. I think diverted the conversation, the tears stopped and she was fine like normal.
So aibu to think this is emotional blackmail and how can we get it across to her that this is not OK?
