Mozza,

When people use rationalizations, it is for the two main reasons:

-deflecting responsibility for one's behavior

-protecting themselves from perceived hurt/reality

The first category tends to be people like the 13-year old boy who didn't finish his homework like he was supposed to do or abusers who claim that their wives made them that way.

The second category tends to be people who are in situations that are very painful for them. It is a self-protection mechanism.

Dig deeper and ask yourself why you would want to "rationalize" your W's OM as a new boyfriend and you as just a XH. Why is that, Mozza? What are you gaining by that type of thought process? Which part of the small child in you are you protecting? What old wounds are being brought to the surface?
