"I had to try. And I did." His voice was lifeless. "But God knows, I don't want anyone but you. I don't even want to want anyone but you." He reached out, trailed his fingers lightly through her hair, fingertips brushing her cheek. "Now at least I know why."

Clary's voice had sunk to a whisper. "I don't want anyone but you, either.”
