What should I do :( ?

I've been hooking up with this guy who I work with and we told each other that we had feelings for one another. I'm 26 && he's 30, sometimes he will come over and all we do is just talk and cuddle. When I ask him does he sees us being more than a hook up he says he doesn't know or he can't guarantee that it will be a thing in the future. I explained to him that I don't want to waste my time and if he doesn't see us being in a relationship then we should just be friends with benefits. He got mad last night and left when I told him that I want to be nothing more than fwbs because he isn't sure if wants something out of this.. he usually gives me a hug and a few kisses when he leaves but he only gave me a hug.. he slammed my door and when I asked him was he mad about what I wanted he shrugged it off like he didn't care. I haven't heard anything from him.. what should I do?
