i’m confused

i (21f) met a guy (19m) while I was on vacation. we went on a date and I really liked him, we talked a lot and for some reason it almost felt like i had a soul connection with him. he is everything I've ever wanted in a man. we met again the next day and we ended hooking up. it was kinda romantic and he's super respectful. i flew back home today and he hasn't texted me since. I was expecting him to text me something before my flight since he knew i was flying out this morning. but he didn't. I feel so weird now? idk where we stand. the day we said our goodbyes he asked me when I was going to be back and I said I'll be there soon (my bestf lives in his city), to which he said if I was going to be there in the next 6 months and I said yes. I don't know what to do now, should I reach out to him and say something? because nothing about the whole thing was casual to me, but idk if he feels the same.
