Thanks for all the advice.  I hope I dont have to go to the authorities, but I want my daughter to be safe.  Someone suggested maybe her changing schools, although that would be a good solution, and give her a fresh start but she is so involved with school, she is on the dance team and really enjoys that part of it.  Please keep her in your prayers Ill let ya know how it goes.  Thanks
