Does he like me?

I like this guy but I have no idea if he likes me back, even as a person. My friend asked him if he liked me and he said no and she asked why and he said cuz she's ugly. I confronted him about it the next day and said why did you call me ugly and he said it was just a joke. But when we went to school the next day he acted like nothing ever happened and was just acting normal. I need help!! What do I do???
