I'm getting mixed signals?

So this is a long story, but there's a lifeguard at my pool, he's really cute, we've talked a couple times but it was basically him just asking my name and grade, and then he followed me on twitter. My friends convinced me to DM him, so i did and our conversation was me saying hey, him going Hey? I said Sup, and he didn't answer. This was like....a week and a half ago, but he messaged me last night and said hey and i said Hey and he never answered, but he's been on twitter....i'm so confused.
ok asshole. i never said he liked me, I'm meaning why is he messaging me if he's not gonna answer

He did absolutely nothing to show he liked you that way. Why are you confused?

Try good old human conversation. Like hello how are you. So how are you etc.
