Hottie😍

So I'm 15 and there's this guy in my drama and science class and he's really cute.  The first day of the semester we were playing a "get to know everyone" game in drama and we all had to stand on our chairs in a circle and organize ourselves in alphabetical order but we weren't alowed to walk on the floor, only on the chairs and I had to get past "hottie" and we got pretty close lolol and being the clutz that I am I fell and he caught me and we both looked at each other in the eyes and it was kinda weird because I hadn't felt that way before.  He had a girlfriend at the time but she was in grade 8.  Naturally, I decided to stalk his Instagram and I noticed that they broke up.  Then within the next couple days we were playing another game and my teacher said grab someone that you haven't worked with before and he quickly looked at me and said my name and in my my mind I was like "Oh hey lolol ok omg." Omg I'm such a dork hahaha.   Does anyone have any advice?😊.
