What should I do?!

So yesterday, my school had a trip for snow tubing. I had an amazing time with my friends. But, I didn't really talk to my ex / Bestfriend because he was busy having fun. So after the trip, everyone got on the bus and was heading home. I chatted with a couple friends include my Bestfriend but we haven't sat next to each other during the whole trip. So our administrator wanted us to sit next to each other because he knows that we really like each other. So I moved to him. We talked for a few minutes then he wanted to sleep because his side was hurting from the trip. So me being a asshole had tired to make him for get about to pain being picking with him like poking and slapping, etc. He got mad then I accidentally broke his beats. So we got into a huge argument then we stop talking. I was really upset because I wanted to ask him back out later on that day because we were gonna hang out like always. But now I know I fucked up badly. Like I really like him and miss being with him. Now I'm never gonna have a chance with him.
