My now 9 years old daughter has a friend at school who was her "best friend" .But this girl blows hot and cold whenever this other girl Ava gets in the middle of them and pretty much takes away her best friend. Ava does not include my daughter and their friendship it seems. My daughter gets hurt by this and feels resentful and is emotional after it but keeps going back to this girl who deserts her whenever this other girl comes along. How can I protect my daughter's sensitive emotional heart? This girl doesn't appear to be a true friend. And tattletales on her saying that my daughter said that she couldn't play with other friends my daughter said she's never said this. Also this seems emotionally very very sensitive..
