to be or not to be ?

A guy that I really like and have liked since high school (both in our 20s now) is deployed. We've never been official but we've always had a thing and by that I mean sex. He was the second guy I was ever with, and we had flings ever since then. Before he left we had another fling and I haven't been with anyone since him..we still talk & it's been a few months months. I'm kind of putting my love life on pause. My worst fear is he never wants to make this official. Am I wasting my time waiting? Or should I continue to wait and see where this leads?
