Iqqi,
It is my opinion, big picture, your friend could have been
any woman there that looked, and behaved, in a way that attracted Crush. I don't think it serves you longterm to focus on the other woman specifically.
You did something that made this guy lose interest in you and move on to another woman - your friend was "next in line" in terms of who he had been relating with through the course of the evening - she really could have been any other woman on his radar that night.
We can philosophize all we want about "girl code" or that your friend didn't stay in her place and only serve as a wingman to your game - but the fact is, your girl friend did everything right to attract Crush - whether intentional or not. This is an opportunity to learn from her.
You say the girl is intelligent, funny, attractive, and ultimately has a good heart. Assuming all things are equal between you two, your friend stayed available to Crush - while you went off to talk to some other guy (and took Crush's interest for granted, IMO.) That is the difference. Crush watched how both of you acted/treated him.
A woman has every right to talk to who she wants, but it is unrealistic to expect a good man to be put "on hold" if she goes off and talks to another guy.
You said you have liked this guy for 6 years and yet chose to spend 15 minutes of choice flirting and connecting time that could have been with him, with Old Acquaintance and not on the guy you really liked. Why would Crush think that after 6 years you are now genuinely interested and not just flirting for sport, when you disappear to talk to another man?
You said Crush had deflected your friend several times earlier in the evening - that was respectful of him, I think. And how did your behavior reward Crush? You went off and talked to another guy.
It may be your right to talk to other men, but the action did not get you the man you wanted.
The pivotal occurance was not your friend, her age, how close she stood to Crush at any given moment. Nor was it drunk Old Acquaintance approaching.
The pivotal moment was when you chose to spend 15 minutes talking with Old Acquaintance hoping

"This... was perfect, as it gave my crush time to miss me and wonder where I was, and of course could create the perfect stirring of competition to heat the situation up."
It has been my experience that as a woman, my seduction time is best spent actually enjoying my man rather than trying to stir up his competitive energy.
I think it is good that in your mind it is no longer "about" Crush... when you move through this to where you realize it is also not about Old Acquaintance approaching drunk later - or about your friend giving or not giving her number... then you are left with your self and the choices you made that night. When you look at what actions brought you connection with the man, and which actions didn't - that is the solution that will serve you in the future. Then you can be friends with the hottest, youngest, most sexually aggressive women and they will not pose a threat to you getting and keeping your Crush. Because it really has nothing to do with other women at all.
With respect,
LL
