Boyfriend trouble

So me and my boyfriend have been together for 4 months, he's very busy as he's at uni (but does it from home) works and does tournaments, I get to see him twice a week, he finds it hard to see me because he's busy, I'm very understanding of it, the other day he said how he doesn't know if we will work because he doesn't have much time, we was together last night and it was good, I just don't know what to do, to make it better, or to improve things, or make him believe it will all be okay?  what do you think?
