Now you know what kind of a selfish jerk he is and will be again. Time to think about going. No, don't pay him until the lights are back on. If it were me I'd be pounding on his air conditioned door to tell him that now!
I see. That makes sense. I have lived with that jerk before and a fool like that only cares about himself and he'll make your life hell if you question him or defend yourself. I hope you can get away from him.
Is there a way so that you can do that, too?
