Ok so long story short

I have a crush on this guy I’m 14 and he is 14 but I’m older ok 😂 and we only have one class together idk when I started to like him but it was around the beginning of the year and we have gym together. 2 of my friends have asked him if he likes me and he said no both times but I don’t know what his reaction was. But in gym when we have like free time with like volleyball basketball and soccer in one gym, soccer is upstairs and the rest is at the lower gym but ok. He would catch any chance to look at me for just a quick moment. I had this cute crop top on and tight leggings (I literally have no ass) but before class starts we sit on the bleachers and me and my friends were one bleacher lower than them and he made eye contact with me and he kinda had a tint of pink in his cheeks. And me and my friends were complaining about how hot it is and I had shorts under my pants cause they were see thro and I told them that I could take my pants off and he looked and me when I said that and he started to kinda smile with a red face and like grinning and it was cute. When class actually did start that’s when it happened. Me and my friends played volleyball and he was with his friends playing basketball like at the goal right next to us. (The gym is really weird) and he would glance at me and I would glance back time to time, and when I went to get the volleyball he would watch me and when I would be like a little close he would ask for the basketball and shoot it when I’m RIGHT THERE and he would make it and we make eye contact and I was like huh damn cause it was a 3 pointer and omfg I went back to playing and when my crop top went up it showed my stomach and I looked really skinny and I kinda am cause I am on a diet but he would watch every time I served the ball. After that day he became distant and I don’t know y?

He doesn’t even say a peep to me after my friend gave him my number but she said that he kept it in his hands and looked at it for a few minutes and then threw it on the ground NOT EVEN SCRUNCHED UP...... and now we don’t act the same. What should I do? My friends think he likes me but I say he doesn’t. What do u guys think can you help me?
