I do agree there is atraction in a girl/guy friendship somewhere along the relationship but things can change. My best buddy in Highschool was a girl. Yah when we first were friends I had a crush. Most of the time she had a guy and I started to fall for other girls and she became like the sister I actually get along with. Now she is married and we are still good friends but we talk very little though because of distance and we have our own lives..
I know a lot of girls who i consider a sister i never had...though most ppl don't think i'm tellin the truth when i say that.
I don't know...i mean, yeah a lot of times one or the other wants something more, but i really think in some cases there can be true guy/girl friendships
