"Let's not fool ourselves, Diego, I gave you everything that is humanly possible to offer and we both know that. But still, how the hell do you manage to seduce so many women when you're such an ugly son of a b****?" She continued, "I'm writing to let you know I'm releasing you, I'm amputating you. Be happy and never seek me again."

Richard Burton to Elizabeth Taylor -

"I shall miss you with passion and wild regret," he wrote. "You may rest assured that I will not have affairs with any other female. I shall gloom a lot and stare morosely into unimaginable distances and act a bit, probably on the stage, to keep me in booze and butter, but chiefly and above all I shall write." They officially divorced in 1974, but remarried in 1975 and then got divorced again less than a year later.

Marlon Brando to Solange Podell -

"In order that you won't think me a complete boor, I am writing you this letter to explain that because of an erratic, flighty, fly-by-night, temperment I wish not to humiliate and degrade your sentiments by seeing you only at my mood's conveinence. Please accept this letter with an open heart as it is written with fourthright sincerity. I’m sorry I could not have tried harder to be less self indulgent and theirwith, a little more compatable."

Jackie Kennedy to R. Beverley Corbin Jr. -

In one letter from January 20, 1947, she wrote: "I've always thought of being in love as being willing to do anything for the other person, starve to buy them bread and not mind living in Siberia with them, and I've always thought that every minute away from them would be hell, so looking at it that [way] I guess I'm not in love with you."

Simone de Beauvoir to Nelson Algren -

"I am not sad. Rather stunned, very far away from myself, not really believing you are now so far, so far, you so near." She wrote, "So, I'll wait. When you'll wish it, just tell. I shall not assume that you love me anew, not even that you have to sleep with me, and we have not to stay together such a long time, just as you feel, and when you feel. But know that I'll always long for your asking me."

With a mixture of pain, bewilderment, and denial, Wilde wrote, "Your pale face used to flush easily with wine or pleasure. If, as you read what is here written, it from time to time becomes scorched, as though by a furnace-blast, with shame, it will be all the better for you."

For years, Douglas claimed that he didn't know about Wilde's prison letter. Upon his release, Wilde turned it over to his friend Robert Ross with instructions to make a copy and send the original to Douglas. According to Douglas, Ross never did. But what Ross did do was publish excerpts from the letter several years after Wilde's death under the title 'De Profundis.'

Edith Wharton to W. Morton Fullerton -

"I don't know what you want, or what I am! You write to me like a lover, you treat me like a casual acquaintance!" she wrote. "I have borne all these inconsistencies and incoherences as long as I could, because I love you so much, and because I am so sorry for things in your life that are difficult and wearing … Only now a sense of my worth, and a sense also that I can bear no more, makes me write this to you. Write me no more such letters as you sent to me in England."

Agnes von Kurowsky to Ernest Hemingway -

The inspiration for the romance in Ernest Hemingway's 'A Farewell to Arms' (1929) was his own affair with Agnes von Kurowsky, a Red Cross nurse he met while recovering from a shrapnel injury in Milan, Italy, during World War I. When he had returned to the US to find them a home, von Kurowsky sent him a breakup letter where she confessed that she probably never had been in love with him.

Agnes von Kurowsky to Ernest Hemingway -

She wrote on March 7, 1919: "I know that I am still very fond of you, but, it is more as a mother than as a sweetheart. It's alright to say I'm a Kid, but, I'm not, and I'm getting less and less so every day. I tried hard to make you understand a bit of what I was thinking on that trip from Padua to Milan, but, you acted like a spoiled child, and I couldn't keep on hurting you. Now, I only have the courage because I'm far away." Hemingway was 19 years old and von Kurowsky was 26.
