About the girls having guy friends....I'd hope that the guys I date or my future boyfriends would trust me enough to know that my guy friends are just that, friends. It sounds, 02_Si, that since you trust this girl that you should have nothing to worry about. I understand your concern about her guy friends, but if they're anything like my guy friends, they're more like brothers.
As for why some girls have more guy friends then girl friends, honestly, they're just more fun! I have the most fun hanging out with my guy friends. I can really be myself and they give me a really good look as to why guys act the way they do, how they really feel about the opposite sex and their viewpoints on situations.
