In my opinion it despnds on the stant of the reltionship. It's quite difficult to be just friends when, you are a women and the other person is a man, or just let's say "the oposite sex". Sometimes you just start as friend and you tell each other confidences and the problems you have, but other times you forget the rules and you start feeling something different for the other person and you confuse it for love!
Have you ever had this experience?
