Women, generally, put their entire stock in a relationship. They define themselves in large part by the man their dating. WHen she goes down and they get dumped it fucks them up like crazy. I used to be the nice guy on the other end of the phone listening to their grievances. No more though. The good thing about getting older is that you see the same shit over and over and you learn from it.
The worse thing ever for a woman is to be dumped and then you start dating someone hotter.
