Unfortunately, I have a daughter who is a narcissist and has done this to her own sister. It's very upsetting because she has my sister believing her too. I have very little respect for my sister now. I thought she was much smarter. It happened before in our family with the same daughter who contributed to all of the family hating my husband even when the other 2 sisters said her claims were not true. So, this means my sister is just a traitor and so is my daughter. It hurts. I'm glad you were able to find a positive lesson out of the painful event. But I'm sorry you had to hurt along the way.
