What is love without feelings?

I was never tought to care for any one, to act without remorce in anything that I do. For twenty-five years I felt nothing. Life and death, pain or joy. All the same to me, I did not care, and after five years of trying to change to have a family I cannot tell if I know how to. After so long, how do learn to change? What does it mean to "love" ? "Love is a word that means an emotion, yet love is an emotion that means more than words can ever say." How do you share what you do not know, or know how?
