The idea that women isolate their attention needs towards one exclusive male is patently false. In so many instances women prove by their behavior over and over that this simply is not the case. How romantic a situation it would be if this were in fact the case, but it simply proves this attention dynamic that the more despreate the woman the more ardent she would be in maintianing this fantasy for herself and any guys so deprived of femminine intimacy.
You can belabor that women are only interested in singular male's attention, but easily observable behavior constantly contradicts this. To imply that women only primp and prepare meticulously for a single male's attention is disingenuois to say the least. And this very disingenuousness only bolsters my position that women, by design, are seeking the best possible mate from the widest pool of eligible males in their attention requisites.
It's simply false to suggest that women would maintain a ritual like 'girls night out' and deny that it's very intent isn't to attract as much male attention, from the largest possible pool, and in the same breath imply that it's true intent is an effort to make a single, paired, male more responsive for attention. This is a lie of the highest order and one intended to distract a man from the real purpose of the event, which is simply a concentrated effort to accumulate as much self-affirming attention as possible in a single evening to compensate for a recognized deficit of this attention,
One other point I should illustrate is that women are rarely (if every) conscious of the true motivations of their behavior. So while a woman will say she is earnest in her desire to maintain some semblance of a platonic friendship (however she perceives this) with a guy, her behaviors will ALWAYS belie her true motivations and this, simply put, is attention for self-affiramtion developed and socialized for the better part of a lifetime. It's far more comforting to convice oneself of the altruisim of ones own intent regardless of the real underlying motivations that inspire these rationalizations and the behaviors that accompany the intent.
The simple message here is, observe what women do as a whole and use this information to make predictions of their behavior rather than believing wholesale what a few of them 'say' is their motivation and intent.
