Can Anyone Help Me With This Boy'?!?

There's this boy that I've had feeling for for awhile now, an at a party about a month ago he kissed me. Well I liked him already so that was good for me wll we have the same best friend an he told him he liked me an was going to get with me. Well the next day he had a game an we went an watched his team an he acted like he didn't like me so I didn't think anything about well a week went by an I didn't see or talk to him til friday an he was accusing me and my best friend of liking each other. Which wasn't true at all an now he acts like he hates me. But everybody keeps telling me not to worry or just move on. But I have a feeling that I shouldn't move on. Any help'?!
