The more you stay with someone or constantly hanging out with them the more you will likely fall in love, or perhaps feel confused and think that it is love when it really isn't. You just have to differentiate between friendship and love and know how to handle and confront both subtle-ly and maybe straightforwardly. Well fortunately i haven't experience this situation and unfortunately i haven't experienced it. I would like to feel the happiness of love and the bliss that comes with it. But on the other hand i would not go so far to the extremes to achieve that goal, to me it is important but not as half as important as trying to be succesful in my career. If this does happen, i'll just go with the flow and see where it leads and if i fall, i'll just get back up and put my head in the game once more.
