Gerald and Thayer nailed it. Take points for G, he is the master pimp. If she hasn't realized the JMU is full of hot chicks that surround you in your classes, then this was an issue that was going to come up soon anyways. Tell her that she needs to calm the fuck down or walk away. When she wants to act like a grownup and realize that you can have all sorts of friends without even thinking of cheating, then you will allow her to talk to you.

edit: point out that she needs to piss off, because it's exam week and you've got enough stress in your life right now without her fucking up the stable part.
