Should i talk to him or leave him alone?

so like, we became really close on this overnight thingy<3 and like he said that we needa chill sometime. then like four days after the overnight he came to my grad. Since then we have only like said a few sentances over all of summer. i kept asking him if he wanted to chill ( loll only once ) and he was like where are u? and when i told him he stopped talking to me. Hes like three years older than me tho and dont bich me about it kay?
