I don't even know how to word this.
I'll try my best.
Your husband/partner asks you to do something (something petty like turn off the PC) and you say no. He then shouts at you to do it. You say no. He then goes nuts and starts shouting and screaming in your face to turn it off and threatens you.
Would you
a) tell him to fuck off an ignore him
b) consider the possibilty that he may hit you and turn it off
c) turn it off straight away?
