So confused!

I met the love of my life 2 years ago online (by accident!) but he lives in Arizona and I live in Canada. We are both 17 but he has graduated. He wants to come up here for college but he doesn't have the money, so it could be another couple years before we actually meet.

He's been with me the whole time I've been through anxiety depression and an eating disorder and provides constant support and will stay up all night just to talk to me if I'm having a terrible night.

I just don't know if I should keep hope and stay connected with him, even if it will be years before we meet, or if I should face the fact that while we go to college in two different places and could meet other people and lose interest. I'm afraid of getting hurt because he's been the only one there for me besides my immediate family. What should I do??
