Did he just used me...?😔

Hi so i been seeing this guy for about a month now. We met on okc dating app. We been on dates and I thought he was different plus he would show it to me. He admitted he has feelings for me. He compliments me all the time on how pretty i am and always stares at me. Our texting was non stop. He even deleted the app because he said he didn't need it because he met me. His university is an hour away. And wanted to get serious after he graduates in april. Well yesterday was my first time sleeping with him. And sex was different from guys i been with. He showed me he cared and we fell asleep by hugging with eachother. He dropped me home in the morning and after that he was going to go back home then leave back to university. Well he hasn't texted me. Now I'm having thoughts if he just used me. I was going to text him but just said I'll wait. I just don't even know anymore...
