<human>: crush is 16M

I was at a party and all I see is my boyfriend and three other guys throwing punches at each other. They all managed to make each other bleed. Fair enough they were all drunk but they got into a fight over a cup cake. I don't care if you are black out drunk there is no excuse for fighting. 

Apparently they will arguing who would get the last one and it escalated to violence. I want to dump him but I don't know if I am being petty for it like my sister suggests. 

So I don't know if other schools have this but our school every year has a dance for grades (Freshmen, Sophomore, Junior and Seniors) called the fall formal. They host it on different nights for each grade, it normally falls right near Halloween. For some reason the Fall/Halloween is made to be a super big deal at my high school. 

I was suppose to go with my boyfriend but I want to dump him. I don't think people understand I could be dating Chris Hemswoth (celeb crush) and if he got into a real fight I would be turned off. I hate people fighting it's so stupid and brain dead.  

Would it be so wrong of me to ask out my crush/ask him to the dance? He is a really nice guy and my friends brother, I told her I have a crush on him. She told me it's fine if I want to ask him out, just don't mess with his feelings.

Can you give me the gist of the text in a nutshell?
