Honestly, the best thing for you to do is to find some fling or a good friend who you can spend free time with. Someone you can call and hang out with on your free time. It will drive her nuts, and she will probably contact you at first, but don't respond. She will eventually realize that she has lost "the game" and find a new "victim" to ruin bc she will think she has lost the upper hand with you.

It might sound petty, but as long as you're up front and honest with the person you're with about every aspect of your life and situation there will be no harm. Also, who knows... it could turn into something amazing!
