" Stefan was the one who ... the one she loved. But he'd never understood that love was not singular. He'd never understood that she could be in love with Damon and that it would never change an atom's worth of her love for him. Or that his lack of understanding had been so wrenching and painful that she had felt torn in two different people at times. "
