My fiancée and I have been together for 8 years and at first it was amazing now not so much we have a thirteen year old girl who is totally out of control mouthy takes off won't answer her phone stays gone for days and since we moved to Georgia about 5 years ago it's just gotten worse from there she told her older brother he wasn't a part of our family and almost committed suicide by hanging himself in his closest his father found him just in time she cusses us and does what ever she wants to do a year ago she pulled a knife on me and her older sister saying she was going to kill us in our sleep and her father done nothing yesterday my brother that stays there to help out she came at him told him with me on the phone that she was going to bash his head through the wall we are at our wits end please help us

She misbehaves and yet she still has her own phone?

If ANYONE pulled a knife on me... I would be the one calling the police. If they threatened me I'D be the one calling the authorities... I wouldn't wait for someone else to do it. I don't care WHOSE kid it is.
