What should I do, I'm in love with my best friend, Does she feel about me the same way in anyway?

I am kinda in the same situation. But I think you should try to change your attitude and show her that shes not the only and all. Try to become more busy and dont get too clingy go have fun out there and stop contacting her for awhile. She will start to notice how important you are and she will start missing you. just don't act like your really needy show her that you are confident and that nothing can shake you. You might be wondering why shes dating all the jerks when the best guy(you) is around well is because girls like jerks and assholes... so i suggest you to stop being really nice to her and like be a balance between a jerk and a nice guy . just in the middle
