I no longer have a house or car key to my mother's home & car. She has become argumenative regarding her jewerly. According to her, my husband and I are stealing it. It hurts and I can't make her understand that we are not doing this. I have stopped going around because it upsets me so badly. My brother up and moved 800 miles away. I have always been the one close to her. We used to go places with together, talk one the phone several times a day. If she needed help, I did whatever she needed. How do i deal with the complete personality change? This is not my mother anymore.
