Can't tell what this guy thinks of me

Georgia

So a guy in one of my classes started talking to me, I'd turned him down to hang a couple times and I finally did. We hung out super late into the night, he was so fun to talk to. I really like him as a person. So a couple days later I mentioned I had a boyfriend because I didn't want to confuse him about what this was. But I told him that I really liked hanging with him and I hope it doesn't change anything. He reacted very positively, even saying he's love to meet my boyfriend. Now this whole week he's seemed kind of distant, but I don't know if it's because he's stressed (he's having a time with classes) or because he's decided I'm not worth it. Idk I just feel like trash
