Fights

Soo I got into a fight today at school some girl thought I was texting her boyfriend who btw is my cousin so she started yelling at me and telling me to back off and stuff and of course I’m trying to keep calm and my composure and she said a sentence the made me pissed af “Fine you can have each other he’s a useless piece of shit anyway” my cousin was listening to that and I’m here full on done with her shit and this was at lunch so I got up from my lunch seat went behind her and slammed her head on the table grabbed a lunch tray and smacked it against her legs I pushed her on the seat and she trued to punch me so I ended up grabbing both of her wrists and she kicked me in the stomach all I got was a bloody nose and bruised knuckles she got it worse her grandma apparently wants to “sue” me -.-
