And because I'm so out of control, I can't help myself. I'm not even mine anymore, I'm yours, and what if you decide that you don't want me? How could you want me like I want you?"
He was quiet. He wanted everything she'd just said to be the last thing he heard. He wanted to fall asleep with 'I want you' in his ears.”
