First of all, please don't worry too much. The fact that you've caught his attention even though you two are far away from each other should already prove that he's willing to wait for you.
If you guys are truly inlove, distance would not be an issue. My boyfriend and I used to be in a long distance relationship. He was living 12 hours away and he was still in school while I was doing my OJT. There would be times that he'd message me that he'd decided to ride a bus from where he's at to where I am simply because he misses me. I would also do the same with him. We'd only meet once or twice a month, but it didn't bother us because we knew that this was for our own good.
Are you in a relationship with him now? I suggest you work out a schedule with him. Meeting once or twice a month is possible if you set your hearts to it. And you could always call each other everyday. A short 5 minute conversation can do wonders to a relationship.
Good luck!
