Why cant i tell if he still thinks of me that way, or am i being compltly delusional.maybe hes just a nice guy?

It could be you both are thinking the same thing. Both of you are unsure. I say call him up and see if he has time to talk and work it out. The best way to know is to ask. Just do it in a way that seems sweet and a little naive. So even if he isn't interested in dating, you could be friends.
