We "decided" to break up and i dont know if we did something logical

Me 15M and my ex-gf 16F both had our i relationship and it was the first for both of us at a camp. She lives in an another city which I can not go to and nor can she come to my city, so after the camp ended, we decieded to break up because we had no idea when we could even meet for even a day. We didnt kiss or even hold hands just because we were too shy to.
