sorry but you're too young yet to really know or even be sure of what you really want or what's ahead for you.

let's say you're sure you could wait for her until she's in the right age, what's your guarantee that the girl won't change after the years?

at your age, i am pretty sure it's just infatuation or "puppy love" that you both feel for each other.

so better not just focus your self on her. look around you. enjoy your youth.
