If we discount a woman’s words, but she is quite clearly flirtatious, no matter her relationship status, how do we tell apart the girls who are actually keen to fuck from those who are just admiring an alpha without wanting to jump ship? It can’t be as simple as saying she will be the one sucking your dick, because many women I encounter still want to be pursued … though maybe I’m doing that wrong too.

Other times she might just be interested in playing around, she is keeping you interested just for the fun of it. Its just another form of attention whoring.

Its just to easy to blame the guy for not being good enough at decoding female language or actions. The guy might not even have very much behaviour to interpret apart from sparse interaction with the woman.

The “mixed signals” is often part of the message. She is activily trying to confuse you with her actions. The information is not always available because it is being deliberately conceiled. Its active deception.
Maybe signals become obvious with hindsight, when you can view the interaction and behaviour in its totality. But that is a different matter.

Much of the article has some sound analysis, but this part gives too much credit to woman and the possibility of rational analysis of female behaviour.
