Sooo true.
You and someone can love each other for months and months, love each other completely and totally and for what you think will be forever. Then the fights begin, and you both say things you never would have suspected each other to be capable of saying. And somewhere in between every little threat and curse word and I hate you, you realize, in a moment of cool, passive clarity, that love is gone, and you're left with nothing but memories and emptiness and hate and bitterness and, maybe, a little bit of yourself, if you're lucky. We are fragile things.
