My advice is to just remain friends. It doesn't mean that you don't care about each other but the two of you are young, and maybe by remaining friends, once you are older, you guys can see each other whenever you feel. This way you don't miss out on your own personal growth, but you can still be in each others lives (via facebook or text messaging).
I'm not good at beating around the bush or sugar-coating things. My responses are never personal vendetta's on your emotional state. It is what it is, whether you choose to accept it or not. <3
