She didn’t understand that. “How can anyone be afraid of love?””How can they not?” His face was completely aghast. “When you love someone… truly love them, friend or lover, you lay your heart open to them. You give them a part of yourself that you give to no one else, and you let them inside a part of you that only they can hurt—you literally hand them the razor with a map of where to cut deepest and most painfully on your heart and soul. And when they do strike, it’s crippling—like having your heart carved out. It leaves you naked and exposed, wondering what you did to make them want to hurt you so badly when all you did was love them. What is so wrong with you that no one can keep faith with you? That no one can love you? To have it happen once is bad enough… but to have it repeated? Who in their right mind would not be terrified of that?
