My husband had an affair with a woman who is now claiming she is pregnant with his child. She first requested money for an abortion, then changed her mind and threatened to ruin us, then called asking for more money than the original request, then again changed her mind and is threatening my husband and has included my and my 10 yr old daughter in her current threats. We have not paid her any money to date and just want to get rid of her. We dont know for sure that she is pregnant or that it's my husbands child. She seems to be unstable and I need to protect me and my daughter and our home. Do we have any way to protect ourselves and get rid of this person?
