@latinnova I completely agree that women do many things we think are odd, because...well, they're women. Science has shown that men and women have different brain chemistry in some areas, and neurological differences, if I recall correctly.
The problem arises when a guy, having just been dumped by his girlfriend, absolves himself of all responsibility to improve and remedy his flaws, and dismisses the breakup as 'well, women are like that'. More often than not, the breakup occurred because the man was no longer being a man. The woman's reactions and desire to breakup occurred because he was getting weaker as a partner, beta-backsliding, or becoming a doormat, etc.
It's important to realize where you could have improved. It's also important to realize where the relationship's failure was out of your hands.
Some self-reflection is needed, in order to prevent mistakes that happened in this relationship from happening in the next one. I absolutely agree though, that after a certain point, worrying about the how's what's and why's will prove more harmful than good. @OP, know when to stop the analysis ("Analysis is paralysis", a good quote I read here some time ago) and let go. Take what you can from it, and move on stronger into your future with women.
But, that requires some self-reflection. For a woman who I assume you spent a good deal of time with and cared about, some consideration of where things might've gone wrong (whether or not it is indeed your fault) is in order. You can then attract even higher quality woman in the future.
