A woman's friends are the worst. They definitely go with the pack, and want who everyone else in the group wants. I've experienced both sides. Either they all wanted me, or none of them did. Even if some of them originally were interested - they changed their minds almost instantly, once they "discussed" things with their dumb friends - until they realized that other women wanted me. Then, it was back on again. Same goes for co-workers. This happened to me countless times.
Quite retarded, they are. No minds of their own; going with whatever is cool, and whoever they all agree is "hot". It's like a damn herd. They are always asking for their friends' opinions on this garbage, and chasing after who everyone else wants.
They always discuss these things with their friends. Always. If you casually tell one of their friends that you asked her friend out in a fly-by conversation - they'll say, "yeah, she told me". And if that friend you're talking to doesn't like you - neither does she. This was discussed; you were viewed as not good enough; blah blah. Until that friend likes you because other women do - now that original person likes you. I **** you not. They actually do this. They want acceptance, and the coolest / hottest guy around - as per everyone else's opinion.
Another thing you gotta watch for is sabotaging and **** blocking. They're always competing with each other, and want the best relationship out of everyone in the group. If they're not happy and/or single and lonely - they don't want their friends to be happy and dating, and not focusing all their attention on them. They want everyone else to be single and unhappy, so they don't feel lesser than them. Experienced this before, too. Overheard a lot of **** that was fed into their minds - as the friends acted nonchalant about the whole thing - as if they were just giving friendly advice that was in their best interests (Ha ha... No).
Their friends opinions are always sought after, taken into consideration, and followed - especially if the girl in question is a follower. Most of them are, and want to "fit in".
Then you have the guy friends, which are the worst. But I don't need to get into that.
This is mostly the status *****s, though. A lot of hot / young / popular / superficial girls fit this bill. The decent ones don't care too much about this stuff, and don't have retarded friends who look down on those who aren't one of them. But, remember: you are the company you keep. She would have probably followed the pack eventually.
