She wants to spread her wings and date other guys, and why not, at her age? You aren't married, and I hope you are not even remotely considering marriage.

If you love her, I think you should break up. If you guys are meant to be, you'll find your way back to each other, but she wants to see other guys. That's just the way it is, and honestly, there's nothing wrong with that-- she's not even old enough to order a beer yet, she's hardly old enough to make a wise choice re a life partner. The Air Force sounds like it would be a good choice for her -- both financially and education-wise, and I hope that you wouldn't stand in her way because of your "love".
