I can't get this girl to stop harrassing me...

I'll start with a little background information. My boyfriend and I were together for three years, and we broke up for almost two years. We always stayed best friends. I started realizing I still had feelings for him, and I told him, which is when he confessed to me he had been dating someone for a couple months. Nothing too serious, just a dinner and a few drinks out here and there, and their relationship wasn't very physical. He told this girl at the time he didn't see a future with her, and he'd like to remain friends. That was a year ago. During that time, we have both had to block her and her friends for sending us threatening messages on Facebook and "stalking" us online. We both work in a restaurant in a small town, and she comes in quite often with her friends, drinking, always making snide comments and acting ridiculous to get attention. She even went so far as to tell my boss I was a bitch, and a terrible bartender, and proceeded to tell my boss the entire personal story behind why we don't like each other...only from her point of view, which is clearly delusional. At one point she started calling me a bitch, and was escorted from the building. I don't know what to do at this point, I seriously think this girl is crazy! HELP! And I don't wanna have to punch her and go to jail....

I think you should talk to the police if she is threatening you... That is not normal behavior... I am a psychology major and she is showing signs of serious mental issues. She could actually harm you physically it sounds and if she is spreading lies to your boss, she could hurt your work life.
