Confused... what is it?

I know this guy for some 6 months now. We started with frens and then it took off to very personal level of discussion. We planned to go out etc but a day before he reminds me that we are just frens. All his feelings and emotions are for me is as a fren.
We spent a night together but since then I don't feel the same for him. Now he talks to me as we did b4 but seems I don't have any reply and his asking me not to ghost him.
I am so confused. what does he actually want from me?
