Does he like me and should we be more than friends?

kso this guy i really really like just broke up with his girlfriend, and tells me on and off that he likes me and thinks i am cute and stuff. but then when i talk to him the next day he just acts as if nothing happened and treats me like a friend again. i want to be more than friends but i want him to admit it first, do u guys think he isnt admitting it because i havent yet? why is he like that one day and not the other? please help. thank you :)
