I was just friends with one of my ex-girlfriends for over two years before we started dating, and almost four years with another. The Friend Zone doesn't exist. It's just an excuse guys use so they can tell themselves that, if circumstances had been different, the girl in question would definitely have fallen far them while in fact she probably never would have been interested in a romantic relationship.
Isn't that just called breaking her will? I've been friend zoned, but only for a couple of weeks max. I try and get my feelings out pretty quick, so we both know where we stand. If she's game, great. I'f not, I'm happy to be friends, but at least there's no pent up feelings...
