The pain of love is the pain of being alive. It is a perpetual wound.
Author, poet, playwright Maureen Duffy (1933—) is a notable contemporary British poet, playwright and novelist. She has also published a literary biography of Aphra Behn, and The Erotic World of Faery a book-length study of eroticism in faery fantasy literature. Her work has often used Freudian ideas and Greek Myth as a framework.
Yet, as I’ve heard, pain is inflicted on those who have a heart in the first place and one has never felt pain until he or she has felt love.
