Some back story: I'm a 17 yo kissless guy that have no social problem, and some social circles. I have the problem of falling in love with every girl.

Well, in the beginning of the year, i started to like this girl, and all indicates that she was liking me too. The story goes on and on, with some flirts and some sexual indicators, until last week, when she called me to watch a movie, but ended blowing me out. Yesterday she asked if i wanted to do some run with her, i obviously accepted and started to feel anxious. All ends here, today i went to a run with her, and when i was dropping her home, i started to pull her closer and closer to me, until the point she said "no, no 'John', we are just friends.

  Well, this was my first REAL rejection, and i invested too much on this girl. I'm much happier now, and will never again invest that much in a girl.      Never felt this good. 

EDIT: After 2 weeks, i picked up a fucking girl, and she is fucking beautiful. Just needed some courage, thank you all!
