How to lose feelings for a girl?

I used to sit beside a girl in class in 2011 and she would always smile, stare at me and be nice to me. Anyways at the end of the semester I added her to facebook and started being mean to her called her ugly, small etc. she just restricted me. Then I kept unfriending her and adding her back and she kept accepting. Anyways I started more convos she responded but then I started being mean again to her and now she just blocks me. I can't stop thinking about her but I don't really like her that much

LMAO TOTAL Tardo Alert

I don't know what a tardo is but I think your just writing short as possible so people actually REPLY but the bluntness of this makes you look harsh but look, I've done that to a girlfriend too. Treated her crappy make her jealous because I'm an insecure dirtbag that feels comfortable out of balance. Addicted to drama thanks to my parents. Maybe you've had a similar upbringing? Because even I wouldn't continue contacting after she unfriended me, that's just tardy

Date guys....less drama.
