The article is mostly just pop culture nonsense. When a woman says to a man, "You're a really nice guy, but I only like you as a friend" she is just saying she’s not interested politely – it has nothing to do with the guy being nice or not.
The article begins with “Are you a nice guy who has always wondered why the ****y guy -- the one who barely appears interested in the girl -- is usually the one who gets the girl?...” I’ve never thought that. I’ve always figured that the reason women liked me was because I am such a nice guy. Of the ****y guys, yea the girls might laugh at them but I’ve never seen girls go ga-ga over them.
The article also continues the myth "Why does the guy who doesn't appear to care as much about the girl get the girl?" Again this is a fallacy. Women don’t chase after a guy for very long that doesn’t or appears to not care about her. The guys who get and keep women always care about their women.
Also from the article “It works like this: Once you need something, or you want it too badly, you forfeit your strength and lose all power of negotiation. You are in a position of weakness and you are perceived as weak. Someone (or something) else is in control of you, the situation, and it's outcome. Men in this situation appear to be anything but confident, strong, and exciting. More, they are perceived as being unworthy and as lacking value.”
Yea, yea, yea. I want my girl friend and I want her badly. She never sees this as weakness. Quite the opposite. She tells me how much it shows my courage. Weak, spineless types are the ones who fail to adequately show their intentions.
This whole nice guy/bad boy talk is just nonsense. If a woman is adequately attracted the niceness or badness really doesn’t matter.
