Ik I'm the problem, should I be forgiven or not?

Idk how to start this. So recently my friend [M] and I [F] got into a heated argument. It was around when my class and i were preparing a welcome back party for my adviser. They created a GC and were discussing about what to bring or what to do blah, blah, blah. Then, out of nowhere my friend started clashing out on why we were being so 'extra'. In my language it's like saying "Why are you guys doing all of this. Yall are overreacting and stuff."

And he kept leaving, giving trouble to the admins of the GC trying to get him join back. Y'all are probably wondering "What if he didn't want to join? You guys should've let him" Mind you. This was the same dude who faked depression for attention. Ik, he probably changed. But leaving is one of his tactics on gaining eyes. So I said to the GC admin

(Ken, just kick him out, if he doesn't want to,then let him be.)

Then, he replied saying we were quote 'Extra' and 'Dramatic' I bit back calling him stupid. + He left.

Ik I was a little harsh calling him (stupid) since I was also angry at that time. And wasn't thinking. After a few minutes I realized I made a mistake, so I apologized that I screamed at him bc he kept leaving and caused a fit. I told him it's up to him if he forgives me or not.

Fast forward of ignoring each other for a month. He kept staring at me like he was disgusted in me, and kept avoiding the places I went to. Even letting me hear his bad mouthing Abt me. I just thought of it as nothing, and that he will cool off soon but I was WRONG. Finally when Christmas break finally ended. I found out that he told the teachers abt me and him being enemies. Apparently, we started doing group projects and he would always say. "I hope I don't end up with her." Clearly letting me hear him. He wasn't even trying to hide it. I wouldn't mind him ignoring me bc it was my fault calling him stupid. But my teachers and classmates finding out? Ughh, the humiliation I faced especially my History teacher. I was about to cry earlier. Anyways this is the half story. I'm so emotionally drained bc of my school work and this problem. I wanted to clarify more things here. But I can't.

I also want to hear his part, since I don't like judging people too early. I'm not saying what I did was wrong. But why? Why did he shamed me in the worst way possible? I can't look at my teachers anymore. I'm almost graduating, and I don't want a bad reputation. The reason why I don't talk to him is because he's probably still angry at me. And I want to give him the space he needs. Please give some advice :(
