HELP WITH BOY this kid keeps leading me on and then stopping what should i do?

this kid told me he liked me and keeps saying lets hook up and stuff and when it comes to the actual day hel cancel but in school he walks with his arm around me and like he seems like he really wants to and then hel say something perverted like send me pics and i say no and we fight and then we make up and get cute again and i keep telling him to stop leading me on bc i feel like im wasting my time and he said im not . SHOULD I KEEP WAITING FOR THIS BOY OR MOVE ON i really really really like him a lot
