How can I win a misdemeanor case it if wasn't my fault and i didn't intend in harming anyone?

I am a 150 pund, 21 year old woman who couldn't harm a fly. For the first time in my life I went to a hunted house. My boyfriend and I read the rules about being in a hunted house. One of them was "you can touch or no one can touch you".

As we enter the hunted house there was a point when suddenly someone came out and scared my boyfriend, my boyfriend accidentally hit or touch a girl that was working there in the face. I didn't know this until later that this happen. Suddenly people starting attacking my boyfriedn, at first I thought it was part of the show but then badwords starting coming out so I grab one of the individauls by the hoody and later to other individuals come out and restrained me. They were all security guards. Now I was charged with misdemeanor for assault, help pleas
