MAJOR ADVICE NEEDED!!!!!!!!!!!!

So I met this guy online (and I know, online guys are not always the dating type) but we talked non-stop for like a whole week. He's in the air force stationed here in AZ and I'm really into military men. Any way we talked about going on our first date and i couldn't wait to meet him cause we text and send snaps all the time. But last Sunday I let him come over and it was 11pm. He had just got to base from a friend house from watching the game and then came to my place. I live a good 40min away from him, and I admit we snuggled, kissed and then had sex. We snuggled again before he had to leave. He wanted to stay the night but i told him i had work 5am and he knew that before he came over that he couldn't stay. But before he left he kissed me good bye and i told him to text me when he gets home. (Which he did that night at like 1am). But our conversations are small now and he barely replies. I know he probably busy cause he's a mechanical engineer on base but I'm worried I just got played.

Please give me your unsugar coated feedback
