I want someone who lives far far away....and age difference?

I was in hawaii and i saw this really cute guy working in a resturaunt, the first time i met him he was taking away my plates. I though about him thw hwole time i was there, i had only saw him once but for some reason i felt like i had to meet him. So finally the last night i was there i walked right up to him and handed him a paper with my name and number on it and he smiled and so did i. I was so proud i had the guts to go up to him, but the bad news is i wish i had done it sooner because we could have hung out, but now im over in california. He did text me wheni was on the plane then i replied and he didnt, now for some reason im freaking out. I guess deep down i know we will never be together, and he probly wont go to that much trouble to talk to me, but i feel a very strong attraction toward him and i cant get over it. Might i mention i think he is 18 because he was a waiter, but im only fifteen so i cant just travel over there when i want, but my parent said that we will go there for vacation again. I font knwo what to do or how to deal with this, all i know is that i want to have at least a friendship with him please help me im stuck and confused!
