Has your spouse ever really hurt your feelings during an argument?

When home truths start coming out, tempers start to fray and bitter yet true words come to the surface, what happens? Do we accept the criticism and try to play things down? Do we really start considering packing up ( because when we start to hit wounds with heavy artillery, it’s the beginning of the end )? Do we hit back softly with our own weapons? I think that once certain stuff is said, there is no taking it back, it really cracks the glass. My point is, should we let pride and dignity take over and get our ticket out of the relationship/marriage no matter how high the price?

Is it better to play deaf and dumb and let some things evaporate? How do you handle conflict?
