What just happened and What do I do?

Okay, so here's the story. I'm a pessimist. My only friends are girls because they aren't babbling idiots like the guys in the school. Most of the guys hate me because the girls are flocking around me. I don't know why. On the last day of school the only girl who can actually make me laugh came up and kissed be to go into a crowd of girls who squealed while the guys came over and clasped my shoulder, patted me on the back and there were comments of "get some" and "good job" Later when the year book arrived we were the voted class couple, where the class votes who would make a good couple. Now I'm confused, what do I do? Frankly that day everyone came up to me and also her, the whole time I was pissed. Frankly I hate attention and keep to myself. My question is, what just happened? Does she like me or was it pure pressure or wanting attention. What do I do now? I mean seriously, your best friend kisses you out of nowhere, what the hell do I do? We graduated so we got our yearbooks after school ended for the grads. We are going to the same high school with a lot of the girls who are closer friends than others. Please answer this question and hopefully I can help you. Please post actual helpful comments and not the stupid "Sheee likeeeess youuuuu" **** our "get some" crap....
