ok so this is a bit long winded... for the last 12 months my dd as turned into a horrible brat. She lived with me up til may last year then her dad who isn't reliable, moves away, loses contact ect (but the kids worship him) moved back into the area. dd made life unbearable at home, starting fights with her younger siblings, rude aggressive to me, ran away from home numerous times ext so she went to live with her dad, thinking the grass would be greener it wasnt, so she made a false allegation to ss that he had hit her and moved back home to me after 3 months. She was really good and well behavied for 6 weeks then she started again and because of the alegations that she had made her brother who lives with his dad wouldn't come to mine if she was there, so she started staying at grandparnets who dote on her. They cant or won't see her behaviour even though 90% of the family don't speak to dd because of how vile she is towards nearly everyone, she has an aunt and uncle who she is lovely with and the grandparents but everyone else can see her what a horrible person she is. Her grandparents sent her home because she started with them a couple of weeks before xmas. At xmas she hit me, because i asked her to clean her room, i rang the police and they have told her that if she hits anyone else in the household she will be arrested. Fast forward to yesterday... grandparents are now speaking to her again like all that she has done is now forgotton, she was supposed to be sleeping at her other aunties but asked could she sleep at grandparents instead, was told no, so she punched her 12 year old brother 3 times, my sister after brother left hers locked the doors so dd jumped through the kitchen window and went to grandparents. I spoke to grandparents and told them what she had done, the great escape through the window, hitting her brother and the vile names she called us and they don't think it is a problem.... they are letting her get away with murder. But because this her safe haven, no they won't turn her away, she is getting worst with me and her siblings. In a few months i am planning to move 25 miles away from where i live, for a fresh start, i'm worried that dd won't want to come and has she has this safe haven with grandparents, don't know how i can make her without her running back here every 5 mins and making a fresh start a nightmare. She is failing at school, stealing, smoking. I have spoken to grandparents about sticking with me their daughter but they won't, it's a small town i live in so banning contact would be futile as she would activly ignore it or get violent with me and they would not enforce it anyway. any advice would be great
