does he like me?

we have said hi and not much else in person but he started talking and friended me on facebook first. I am friends with one of his ex and her brother but i didnt know that cause i jusr ment her. He doesnt really answer to anyones snapchatss but does to mine. He said he would beat up these people making fun of me. He is never mean always nice. He goes to public school and i go to private school but should that matter? He is a year older then me but that isnt that big of a deal is it? Does he like me or not?
