Flirting?

So I like this boy but idk if he is flirting.So he is always like “ew” too me but as a jokey way and it’s too my face aswell as too me not saying it to his friends or whatever,he also puts in this “jokey” voice when he says it.He also tries tripping me up(kicks my feet).Every lesson we have together or sometimes break and lunch our eyes meet(lmao cringe).Yeah so I like him but idk if he’s just being a dick in a friend way or what lol.He has tried to get with me before btw but that was ages ago.He also never speaks to me on snapchat smh :[ but i don’t think he really speaks to anyone anyways unless u speak first.
