(15F) Someone May or May Not Like Me

So... you read the title, I assume. Well. A few weeks ago on a Friday, I was in my Chemistry class, which is 6th period and I have my Lunch period right after Chemistry. We were doing a lab and we had 3 other lab partners, with a girl sitting next to me and 2 guys sitting across from me. I was minding my own business, trying to do my own work until one of the guys across from me, let's call him "Y", said something to me. That I didn't even know he said to me. Until that girl beside me, let's call her "E", nudged me and told me what he said to me. She told me that Y said that he thinks I'm "cute". And I was like, "What???", because no one had EVER told me that before, even to my face, at school. Y then asked me many questions, asking if I played any games and asked about a "Fortnite date" since I mentioned the fact that I play Fortnite since that was one of the first games he asked if I play (Please don't come at me), and saying that we should go on one, and at that point, I was very confused but also very flustered at the same time. Like... I really did NOT understand. So, after Chemistry, I tried to look around for him and see where he sat at Lunch. Unfortunately I couldn't find him. The next Monday, I tried to do the same thing and look for him at Lunch. Which, I DID find him. But... he was talking to another girl. And then he went to go talk to another girl after that. I was definitely jealous about that fact, even though it was only him thinking that I'm "cute". The next day I tried sitting near to the table he was at, which he was, again, at that table. STILL talking to the same girl from the other day. He didn't talk to another girl like he did the day before, I don't know why, but he didn't. He did the same thing the next day and the next day, but I don't know if he did the next day because I wasn't near that table (I was later to lunch than usual), but he probably was talking to the same girl from the last few days. This made my mind go absolutely crazy because there's no way a guy would actually say to me that he thinks I'm cute and just go on the next few days without even mentioning it to me again. Because after that Friday when Y said to me that he thinks I'm cute, well at least after Chemistry, he never said anything to me ever. (It's been Spring Break so I haven't been to school since the 7th of March/this month) So I've been second-guessing all of this but I don't want my heart to be too broken if what he actually said to me wasn't true. All of my past experiences with my exes is why I'm second-guessing all of this. And with how many times he's been talking to the same girl every day I've seen him talking to her. Do y'all think he likes me? Or am I just overthinking this and should move on?
