How do I get over this girl and move on? (long question)?

(1) Some girls DO like nice guys, and sometimes the nice guys break hearts too. No one is perfect. (2)Focusing on something else other than your feelings for her is a good idea. Or if you want closure you could just be honest and tell her that you have liked her for a while and that you were hurt by the way she led you on by not flat out rejecting you. But if you are too shy for that then just focus on moving forward in life and you'll find someone else. (3) Just because you find yourself attractive doesnt mean women will or that you could "get most girls" That is an offensive statement and perhaps that attitude is part of the reason she isnt attracted to you.
