How do i get over my first and why is she doing this to me?

this sucks. i'm still not completely over my first love...and never will be... that was 5 years ago. If nothing happens between you again then the best thing you could do is use this as a stepping stone to move forward and learn from your mistakes...it hurts at the beginning but the best thing for anyone in this position would be to be with your friends and the people that bring out the fun in you....people will come up with all different bullshit like "shes not worth it, blah blah blah" but its only to make you feel better. here are the facts...you WILL miss her for a while...i dont know how long but you will. in those periods...be with your friends....thats what i did....i got over it quicker than i thought...i thought my life was going to be boring and not worth it and whatever...but youll eventually meet another girl, maybe 10 other girls and eventually you'll see your ex is changing and you wont find her attractive anymore... sure you'll miss the times...but you'll have better times with other people. i bet your still very young.
