Dreams come true?

I had a crush on a boy and one night I saw him with a friend of mine and I started talking with him. We were a little drunk and when it was time to go home I asked him were he was sleeping and he replied that he didn't knew. As a good person that I am I offered him my couch and my friend that knew him was supposed to also stay there. As we are going to my house he asks my friend if she didn't live near there and she caught the signal and left. When we finally get alone he grabs me and kisses me, we talk a little and kiss some more and I ask him what he is looking for because I was not looking for a one night stand. Not because it was him but because I just didn't want a one night stand with anyone. I told him that and I also told him I was a virgin, he answered me that we would have to talk to see what would happen. It happened. We had sex. The next morning comes and we talk a little and then he leaves without a hug or a kiss or even an handshake just a goodbye. I followed him on IG and he followed me back so I sent him a DM. I could tell he wasn't really interested in talking with me. He told me he didn't want to have anything else with me but he told me we didn't have to be in bad terms, I said OK and told him that it would be cool if we could stay friends. The next day I go check the app that tells you if anyone unfollowed you and there he was. He had unfollowed me. I really wanted to ask him why he did that but I just unfollowed him back and deleted our conversation. Did I do the right thing? Am I right for feeling hurt and used? I just needed to get this out of my chest.
