Im sorry i absolutely lose my shit when he has OBVIOUSLY has done something to fucking piss me off!!!! Im sitting here trying to tell him why im angry and his stupid self just keeps saying that. I absolutely lose my goddamn fucking shit!!!!!!!

Update: I should clarify! When we are arguing and what not I have already explained to him what he did that made me angry. But yet he continues to do the same thing!
