If there is only one in the world who knows 'I'

"I'd obey you."

"Now you see why I won't do it. I won't try to stop you. I love you, Dominique."

She closed her eyes, and he said:

"You'd rather not hear it now? But I want you to hear it. We never need to say anything to each other when we're together. This is--for the time when we won't be together. I love you, Dominique. As selfishly as the fact that I exist. As selfishly as my lungs breathe air. I breathe for my own necessity, for the fuel of my body, for my survival. I've given you, not my sacrifice or my pity, but my ego and my naked need. This is the only way you can wish to be loved. This is the only way I can want you to love me. If you married me now, I would become your whole existence. But I would not want you then. You would not want yourself--and so you would not love me long. To say 'I love you' one must know first how to say the 'I.' The kind of surrender I could have from you now would give me nothing but an empty hulk. If I demanded it, I'd destroy you. That's why I won't stop you. I'll let you go to your husband. I don't know how I'll live through tonight, but I will. I want you whole, as I am, as you'll remain in the battle you've chosen. A battle is never selfless."
