ToFunToDie... most people do not know how to argue maturely, and when you make a valid point, or try to express your feelings.. they are automatically 'being attacked' and go into ultra-defense mode. people are weird.
Years ago when I was stupidly in one relationship and my then gf would endlessly bitch at me there would come a point when I would be expected to come up with some sort of response- for example when the diatribe paused with "what were you thinking???" or "why didn't you call???" or another parent-style demand that I account for whatever transgression I was to have committed... bear in mind I kept silent during the full force bitch fest... when my air space was provided, I'd look at her and say, "I'm sorry, did you say something?" and walk out. This was generally the impetus for argument to escalate to fight and would be better pulled off over the phone when you can just disconnect the call then turn off your ringer instead of having a psycho bitch following you around screaming about how you never think of her while you eye sizable and sharpened kitchen utensils and reflect on her absolute dumb luck that you are not given to psychotic episodes yourself.
