Long Distance!

I have been dating a guy since the end of August. Im 16 on Sunday and he turned 17 yesterday (coincidence that our birthdays are so close together). I live in South East England but he lives nearly 8000 miles away in Bali, however he's originally from Sydney. 
Our relationship is of course long distance but he is moving here next year for university. Sometimes I find it hard to keep a spark even though I know I do love him, I'd just like opinions on it :)
