Ugh. Ideas?

So I was getting really close with this guy and we talked about dating but bc there's an age gap he just wanted to be sure that we liked each other, I can deal with that like it makes sense. But yesterday I told him I was bisexual and he totally changed how he acts towards me, like he doesn't seem the same. So when I asked him last night where this thing we have is going he said that he's not ready for a relationship yet and that we should just be friends with benefits. Literally 1 day ago he was saying how he wanted me to be his and he can see a future for us. I'm so confused and I really just wanna leave him bc if he can't accept me for me then he isint worth it but I like him so much. I don't know what to do!?!?
