You can never unlove her, you just get used to not seeing her, not touching her, not feeling her. Even if you replace her, you'll see her in the eyes of the person you are with. Because you chose that person because she reassembled her. Her hair, the books she read, the language she uses to speak her mind, her love of words and the same disposition about life. Of course, you'll deny all of this. Because you did all this, unconsciously, it was your heart that led you to this. Your heart that aches and breaks for her.
