what is the bottom line to call the police?

I am not sure what is the bottom line to call the police.
Last time, when we were angry with each other, I decided to move out for one or two month. He thought I was going to break up. So he got mad and throw everything down to the floor, including my cloth and glass bottles. Even he cut his t shirt into pieces by sciss and set fire on one of his skirt. And hit wall with his heah. And hit his heah with iron pan. I feel terrible. Nothing I can do but standing there shakily.
