“ It's naive to assume that another person can fulfill you, or save you, if the two things are, in fact, different, and I have never felt that way with Colin. I simply believe that he fulfills an important part of me, and that Robert fulfilled another equally important part of me. The part of me Robert fulfilled is a part which I imagine Colin, even now, doesn't know exists. It is the part of me that can destroy as easily as it loves. It is the part of me that feels safest and most at home behind closed doors, in a dark bedroom, that believes that the only truth lies in the secrets we keep from each other. ”
