Its considerably rarer than you think. Most People confuse it with infatuation, lust, desire, need and other emotions, and a mix of Them. Ive only experienced it once. I married that woman. We had a Bond of unity and interest that transcended every other emotion Ive ever had. We were, to use a cliche, made for each other. She died after 7 years. My life is now ash. I feel nothing. I have No interests. Women hold nothing for me. Everything that made me Who I was has burnt down. Its the most barren feeling I have ever had.
