A huge problem with woman understanding men is that men are trained young to not be open about their emotions because it will make them seam weak. The truth is that it hurts equally as much for a man to get rejected as a it does for a woman. The difference is that girls just won't approach so you average man has felt rejection WAY more than your average woman. That is going to have psychological effects on the way a man thinks. What happens for many men is they start off life romantic and scared. And through rejection getting beat into them over and over throughout the years they eventually stop caring. And THATS when girls start becoming attracted to them. But at that point that romantic part of him has mostly died away because he can't keep banking on the idea of unconditional love after being told he wasn't good enough his whole life. Is that really all that surprising?
