And then, there's Estella

"...life is made of ever so many partings welded together."

'So,' said Estella, 'I must be taken as I have been made. The success is not mine, the failure is not mine, but the two together make me.' 

"The unqualified truth is, that when I loved Estella with the love of a man, I loved her simply because I found her irresistible. Once for all; I knew to my sorrow, often and often, if not always, that I loved her against reason, against promise, against peace, against hope, against happiness, against all discouragement that could be. Once for all; I loved her nonetheless because I knew it, and it had no more influence in restraining me, than if I had devoutly believed her to be human perfection."

"I never had one hour's happiness in her society, and yet my mind all round the four-and-twenty hours was harping on the happiness of having her with me unto death."

- Great Expectations, Charles Dickens
