Well, you could change your screen names and only tell the people who you really want to know it. You can lodge a complaint with whatever service she is using to IM you since its most likely coming from the same IP address, they can figure out its the same person. I don't know if they will do anything, but the more complaints you lodge, the better chance you'll have of getting a restraining order if it comes to that.
