My mother moved in with my husband and I three years ago. I do not want a relationship with my sister and she is not allowed to come into my house or come near my house. I do not have a protective order, it is just a boundry I set to protect my family. She has called the police twice, called my employer accusing me of abusing my mom. These are all false accusations. I have received numerous texts, emails and she has left voice messages with all kinds of hateful nasty comments. Some where threatening me to take me to court. I do not prevent my mom from seeing her or talking to her. I will drive her to meet, I just don't want her near my home. She has mental problems and I just want some peace in my life. I am at my wits end and don't know what to do. Any suggestions?
