Well, good thing is you know you have to move on. Good boy. Now, come on man. You're 17 for Christ's sake. Learn from this past relationship. Make sure you don't make these same mistakes the next time you meet a girl you like. Face it, the girl that you "loved", you let slip right out of your hands! You have to realize and understand the bad moves you made, and make sure you don't make them again. From there, you may improve and have a better chance of meeting a girl just as great.
