Do you think he likes me?

So i have known this guy for like 3 years now. Three years ago we had a cl together in which we got to know each other and i started liking him. However, after the year was over we kinda stopped talking but still said hi when we saw each other. Well this year we have two cles together. And we started talking a lot again and im starting to like him again. Well we sit together in one of the two cles and we talk all block. He tickles me every chance he gets. He know im extremely ticklish, so he does that a lot. And today i hit my hand and he kissed it. We were walking to our next block (which we dont have together) and i told him that he should walk with me cuz i hate walking alone, so he walked me to cl and was late to his own cl. But the problem is that he has a girlfriend that goes to a different school. I know you guys are just gonna call him a player but i honestly dont think he really likes her too much. It seems more like he's just dating her because he knows shes all in love with him. I dont wanna break them up. I'm not gonna try anything with him until they break up but am just curious. Do u think he likes me? Thanks!
