Your wife is giong to try to bait you into fights ... SHe's giong to try to make nasty fights to JUSTIFY leaving... So you dont' give her any...

When she says something mean or tries to provoke an argument, just get up and calmnly walk away... get OUT of the war zone ... HER emotions are rushing around JUST LIKE YORUS ARE...

You need to AVOID that turning into a field battle. YOU CONTROL your emotions and get OUT of the war zone or this will spiral downward.
