I'm sorry you are feeling disconnected right now NF. Its just how I would do it, because I really don't handle people, especially pushy people, in my life very well-I would just flat out tell her that I'm not interested in being her friend and tell her not to come to your apartment anymore. I know that sounds mean and harsh and everything, but I figure when someone's making me terribly uncomfortable, which usually translates into terribly upset, I have the right to not allow them to be in my life. Good luck with whatever you decide.
