Should I stop waiting for him to make a move?

I've been "talking" to this guy since April (so basically, we matched on tinder, he asked for my snap, and now we just snap often every day). We hung out once (he's in the military so difficult schedule, he hasn't been home for a bit) and he'll be home again soon. We're both juniors in college. At first he was very obviously flirty with me, complimenting me, saying we had to hang out, etc. As months went on it gradually stopped until I finally asked him what his deal was a few weeks ago. He said he was interested and that he thought I was dating one of my good friends. He said he's at the point where he's looking for a relationship and that he'll be home sort of soon, but since then, he still hasn't been that flirty and nothing has progressed. I'm not crazy flirty with him but maybe I should be. Like, we follow eachother on Instagram and Snapchat a lot but we don't have each other's numbers or text (shouldn't that be happening at this point? idk). I've been holding out for him because he's pretty much my dream guy (soooo attractive, mature, responsible, etc) but if I'm being honest I'm getting pretty impatient and I'm confused as to why if he is interested he hasn't made any more serious moves. Should I just give up? Or should I wait until he gets home and see what happens then?
