Interesting night

Ok so my fiancé and myself were at his friends house just hanging out and all of a sudden these 3 girls showed up and I guess they were mad at my finances friend.. So he went outside and they started to attack him, kicking punching, and he didn't hit them back so my fiancé was trying to get them off of him and then they started y attack my fiancé which pissed me off so I started to beat their asses. I understand they were mad at my fiances friend but they had no right to put their hands on someone who was trying to calm the situation down, I got so mad, I'm not even a violent person, what would you ladies have done? & I would have called the cops but by time they would have arrived the females would probably have been gone
