what do i do help

So this guy and i have been talking and have been together kinda, its been more than a month now we've made out and like we're basicallt dating but not officially and we hungout alot. anyways we made out a week ago then he went to the states for 4 days with his family when he got back we hungout. I hugged him when i was about to leave but it seemed like he pushed me away. Then i realized maybe i should stop or pull back a little bit, so i did, i left him on open on snap for like 3hours then he snapped me saying Hi, also he's been dry a little bit but i dont know what to do. I still have feelings for him but he's confusing like he seems like he cares but has been less caring i guess than the beginning. What do i do? should i slowly get of this but how please help, i dont want to leave him though but i dont think he wants to be in a relationship also this is in highschool. and yes i know nothing is forever in highschool but still i still care about the present even if the future isnt going to happen with this guy but hwo knows. help please wahhh
