Advice For Long Distance.

I've been dating my boyfriend for 2 years. I'm in my last year of high school, and I'm moving away for college at the end of the year, meanwhile, he'll be staying in our hometown. I'm nervous because he is the first serious boyfriend I've ever had. I don't know what the future holds or if the distance will cause our spark to fizzle out. I feel afraid. I really love him, and I think we're strong enough to make it work, but I need tips. What's the best way to make a long distance relationship work?
