Are we meant to be?

So I may seem young but I want to know if I should continue this relationship. My date of birth is 01/17/03 while my boyfriend's is 01/03/01. We pretty much do everything together when we can, and we think about a future together but. . .is he the right one for me? Will our relationship last long enough? Or should I just give up? I don't want to have my heart broken again. . .
