1. Don't go home this weekend, and don't call her to tell her your not.

2. If she calls you expecting your in town, just tell her you have plans with a girl you met to go out on saturday night. Then you say, opps shes calling on the other line right now, I gotta go, hang up.

Don't answer anymore calls from her for a week. If she still has any feelings for you this will drive her crazy with curiousity
