How do you calm down when you want toexplode?

I am so irate with my boyfriend for acting like im his roommate. He just acts like nothing bothers him and when I tried to talk to him he got up and said Well Im goin tobed now. Goodnight. I want to go in there and scream at him. I wanted to put my fist through the computer a second ago. I really want to just calm down because Iknow if I dont I will dosomething stupid. We have kids aand close neighbors I cant go scream at him like I want to
