I totally see that. I, fortuantely, date men.
I have a ton of female friends, and your complaints are jsut as vaild. Most of them don't hang out together, regardless of anything. I am the lych-pin to their interaction.
I would like to point out two things:
Some men pay for a lot. I know I do ( Does that make me the girl?lol)
And women are always in competition, no matter what the situation. (based on my own opinion)
Let's take Daina. She is a great friend of mine, but when she is single, or alone with any girl, the fights start. Not fight fights, but catty, snappy fights. Sometimes it's one of the others, sometimes its her. The point is, I asked them why it happens. They all agreed that they felt pressure to compete, even when there wasn't a prize. Christ, there wasn't a prize, it was just them. It came down to, after ahour of talking, that they all envyied things about the others, and that made them self -conscience. I don't know if that is true, but if it is, that is scary.
Mind you, I don't hang out with a lot of guys...but maybe that is another thread ....
