All of a sudden you find yourself crushing hard on your best guy friend. Maybe you were always attracted, maybe it’s crept up on you, or maybe the realization hit you over the head one day and you never saw it coming. Now that it has, everything suddenly feels different – you want more. The old joking around feels like the new flirting. The old indifference has morphed into possessiveness or even jealousy. A total lack of curiosity about the future has given way to an excruciating anticipation about what happens next.
