dont think like that man thats ur prob. there are so many girls out there in the world that u can find somone that u love even more than her, i went through a similar situation around the same time u did and u just have to realize its over, it was fun while it lasted and everything comes to an end. Its not going to help u being all depressed and thinking negative that u wont find anyone like her itll just make u even more depressed. My advice is to not call her, as much as u would want to it will only make u think "if only" and u dont need that u need to forget about her and move on because belive it or not she is not the one for u. and next relationship dont ever ever ever ever ever ever ever ever! think ur goning to get marryed and plan ahead becuase if u do it feels like u got ur hopes up for nuthin and makes it feel like a divorce instead of a brake up and i know this one from experience bro
