A little back story, I meet this girl at a house party and it was a good night. that night I made out with two other girls and flirted with this one. well, a couple parties later i messed up with her by doing something stupid. But then she had a cycle of getting cold and friendly. now its my junior year and its been like two years. i still see her around the campus and wonder, Is it worth it if I approach her? and what would I say?
