I friendzoned myself. help?

Been talking to a guy for a month, every day. he seemed very keen, we planned on meeting up for a first day. Then during a disagreement I started I said that we need to be just friends numerous times. He never agreed, I never took it back. Then a day later I try talking to him again, changing the subject, hoping to get back to the way we were and he replies 'as gutting as this is, I think you're right about us being friends' . This upset me bt I realize its my fault for suggesting it in the first place, so I reply 'ok'. Since then we still talk a lot, just not constantly like before, I don't want to be just friends but I worry that if I tell him that then he'll reject me. Is it more likely he said the friends thing simply because I said it first without taking it back? is there a chance he could have second thoughts considering how keen he was on me in the first place?
