Tonight i had a phone call from dp's ex, she was in a right state saying her and dsd had a massive row and dsd squared up to her and went to hit her. Dsd will not listen to anyone at all. She kicked off because she was told she was not aloud to stay at her mates house the night. This behaviour has been happening on and off for the last two years. It goes in good and bad spells. At a loss as what to do now. We have all tried talking to her, grounding her, taking away phone, tv etc none of which work. Any suggestions please needed.
