I have seen countless times in my life, where younger girls, about 18-25, claim they only want a nice man, a sweet, kind and gentle guy that cares about them to go out with. They say they want to be made to feel special. However, these same girls, from what I have seen, end up dating or hooking up with total assholes or jerks, guys that don't give a shit about anything but themselves.

In your explanation, why does this dichotomy exist, when it actually occurs? I am not saying girls don't want nice, kind guys, but in this case, why do these girls turn out like that?
