Confusing crush

What does it mean when a boy says he doesn't know if he likes you or not? I told him ages ago that I liked him as more than a friend and he never really responded to that but we've still been talking for 3 months😒 when I asked him about his feelings he said he didn't know if he liked me in that way or not BUT also said that he's scared bevause we are both going to different universities and all that. We were also at a party together a couple of weeks ago and it was dark and we were sleeping together (fully clothed on a sofa) and we were cuddling and then out of the blue he kissed me and it was really passionate and I'm really confused, this is barely any of the story but I need some opinions or advice :/
