I know a girl who scared me and I think was a psychopath. She latched on to guys and would not let them go. She would call, show up at their houses at all hours of the night, and literally just force herself on to the one she was involved with at the time. I swear this one guy just got so tired of trying to get rid of her, that he just gave up and stayed with her. I don't talk to her anymore (Thank God), so I'm not sure what happened. By the way, I met her through a neighbor and before I knew it, she was coming over my house all the time. If I left it unlocked she'd walk in. If I didn't answer, she'd sit out front in her car and call me until I finally had to let her in. She also conned me out of money every time she came by, her kids need milk, she needed cigs,she needed gas, it goes on and on and on. People like that are persistant and don't give up until they get what they want.
