During a break from drill practice, my boyfriend treated the entire class to popsicles. He miscounted and came up one short. When it got down to me and the campus queen, he handed her the last one. I watched him tear open the wrapper for her with care. "We're done," I said. He looked amused. "Over a popsicle? Really?" "Yep." "Fine. Just don't come crawling back to me." Five years together, and he was dead certain I was bluffing. What he didn't know was that I'd already accepted a spot in the school's exchange program. The moment drill training ended, I'd be on a plane overseas.
