A guy's entire life is based upon rejection. We ask women out, push for sex, take risks. Sometimes it pays off, most of the time it doesn't. We become accustomed to rejection.
You ever broken up with a woman before? They have no fucking idea how to handle it. They've never been rejected. It's so fucking rare for them. Women are generally the ones who decide to be done with a relationship, so they don't have a lot of practice dealing with it. They can't wrap their head around the fact that they're somehow not good enough and go absolutely insane. Their entire lives they've been told that everyone wants to fuck them all the time, so when they come up against someone who says "Nah, I'm good," it short circuits their brain.
You can see this easily if you're interacting with a group of women and spend more time talking to the less attractive one of the group. The hot girls go absolutely nuts because their brain can't figure out why you would be picking anyone over them.
