is he mad or sad at me?

There's this guy I like. He liked me too. And I guess he doesn't anymore. So I just want to be friends with him cause we have class together and we still talk as friends. But yesterday me him and my other friend were all having a conversation. I was talking about this girl I said "ew I hate that person". And he said "oh me? That's why you hate me?" I said "yeah. I don't like you anymore". I was trying tosound sarcastic. But he didn't say anything. And found a exscuse to walk away.... After that me and my friend went to my locker and he was by himself leaning on a locker. He was looking at my friend and had a fake smile and was shaking his head.. I feel so guilty. I was jokingg . I did not mean to say that on purpose... I should of said jk after but I wasn't thinking. I was trying to apologize today in class and say I was joking. But he wasn't at school today.... I'm so sad. I hate being mean to people who are nice to me. I need help. Does it sound that bad... Or will he get over it. Idk what to do.. Sorry if there is misspelled errors in here.
