Some one has killed herself for love of you. I wish that I had ever had such an experience. It would have made me in love with love for the rest of my life. The people who have adored me – there have not been very many, but there have been some – have always insisted on living on, long after I had ceased to care for them, or they to care for me.

– Oscar Wilde

The Picture of Dorian Gray, Chapter 8. Lord Henry is actually envious of Dorian because Sibyl has killed herself for love of him. He views her final exit as her dramatic gift of love to Dorian. It is an experience that Henry wishes he had, lamenting the fact that his lovers never killed themselves but decided to carry on living.
