Much loved daughter lies and steals
I have a 25 y/o married daughter. I was a single mom to her for the first 17 years of her life. She was very loved... by me and my parents. She got married 3 years ago and had an affair after one year. We live in the south, and her affair was with a black man. We have heard she may have been involved with 4 black men in the 3 years of her marriage. She has stolen money from my father, charged amounts on my mother's credit cards, and attempted to withdraw money from my checking account yesterday. She is such a good liar; I'm worried she doesn't have a conscience. I tried to make her feel guilty for stealing from her elderly grandparents, but after yesterday, I am scared she may have a personality disorder. I'm scared I should report her to the police. I'm scared everyone will find out about her, and I'm scared she will ruin the rest of her life. I have a 7 y/o daughter who adores her; I'm afraid I should keep her away from her big sister.
Any guidance will be appreciated.
