I’m so confused

Hi so long story short I’ve know this guy since I was 15 I’m now 18 and he’s 20 I’ve had a major crush on him the whole time. I think he now may like me as well. He is in the army so we FaceTime all the time and he texts me whenever he can. He’s always making flirty comments like saying I’m hot or he can’t get enough of me. It takes forever to hang up the phone because he doesn’t want to stop talking to me buttt then he’ll go and say that he went on a date and how he likes this other girl I’m honestly so confused. What do you guys think?
