Boyfriend leaving soon...

LayLay • 21. I live to make people happy & laugh.
My boyfriend is about to graduate highschool in a couple of weeks, then he will leave for basic in Missouri the last 2 weeks in june. Of course I will go to that ceremony too, but then he will be deployed to Korea. I just feel sadder and sadder knowing that he will be leaving soon. What should I do. I'm 17 & we've been together since my freshman year.
