I purchased a townhouse about 7 months ago. My then girlfriend moved in with me. My sister and her husband also live with me. Things aren't working out with my girlfriend and I asked her to leave but she refuses. She has a child who may be mine (not sure, am going to request paternity test). She has made threatening remarks to my sister. I have called police on her but they say that she does not have to leave----how can I get her out?
