Just keep busting her balls dude, you've got the right idea.
Here's a true story that happenned to me a year ago. Once upon a time, I met this girl at a hangout at our college campus. I talked to her a minute and she left to go see her bf in his dorm room. 10 minutes later, she came back with tears streaming down her face because another girl was in his room. She started to tell me the story, but within 30 seconds of her blabbering, my exact words to her were "I don't want to fvcking hear it, go tell some other dumbass that wants to listen to your sh!t." I promptly got up and went to another area and talked to some other people. I blew it, right? My first impression was probably the worse one I could have made, was it not? Who would have knew that nine days later, I would banging the sh!t out of her in her room. She would then call me at least once a day for the next two months to try to set sh!t up, but I was never in my room. My roommate would let me know she called, but I never returned the calls. And when I would see her, I would fvck her. I never dated her or went anywhere with her or payed for ANYTHING. The moral of the story...BE THE ABSOLUTEY BIGGEST FVCKING ******* YOU CAN BE.
