"As the guy you need to understand that girlfriends, fiancées and wives will occasionally get pissed over something and that you will have to live with it and ride it out until she gets over it."
Funny enough, it matches my experience with an ex-girlfriend of mine. She once hurled abuse at me for two hours, which I just ignored. In the end she was pissed with me for days, because I didn't react when she wanted to pick a fight.
Seriously, did I just run into a psychopath or are women really wired like that?
