So I am talking a guy in the military

I have known him since highschool which was 3 years ago since I graduated he went straight to the usmc when he graduated. He just finally came home yesterday and he will be home for 2 weeks but we are supposed to hangout but he doesn’t txt me back and when he does he doesn’t really say much but hasn’t really tried to make plans idk what to dog friend asked him if he liked me and he said yea she’s cool but I feel like tht is a no. Me and this guy we’re friends all throughout high school and I don’t know what to do help me
