The Problem With the “Girl’s Girl” and the “Nice Guy”

I was recently having a conversation with a female friend when she brought up an interesting observation: why do so many men seem to dislike women who are considered stereotypically “girl’s girls”?
Her theory was that men dislike the so-called “girl’s girl” for essentially the same reason women sometimes dislike the stereotypical “nice guy”: because the behavior can feel manipulative and inauthentic.
I thought she might be onto something.
I’ve had several experiences with women who presented themselves as my girlfriend’s friends, only to start making inappropriate comments or advances toward me whenever my girlfriend wasn’t around. Initially, I assumed they were simply joking. But after similar situations happened more than once, I started asking other guys in our social circle about their experiences.
What I discovered was surprisingly similar.
Some of these women presented themselves as outspoken feminists and strong supporters of other women. Yet the moment their female friends weren’t around, they behaved very differently—sometimes flirting with their friends' boyfriends or attempting to create problems within their relationships.
Obviously, I’m not claiming that every woman who identifies as a “girl’s girl” behaves this way. That would be ridiculous.
But the underlying behavior reminded me of something I’ve seen with the stereotypical “nice guy.”
The nice guy hangs around…
