He kissed me and then left me confused, why?

I have a crush on this guy in my class, he kissed me for the first time a couple of weeks ago but since he acts as if it never happned because he hasn't brought it up. However, he still flirts with me and always looks at me. He doesn't have my number because he never asked for it and I don't know what to make of any of this. Should I just leave it alone?

(The kiss was a french kiss and there is physical contact when we flirt)

We "made out" again and after we did, he told me that he's not a good guy and he doesn't want to hurt me. If that was the case, why bother kissing?
