“I guess I’m not in love with you”
This letter was written by Jackie Kennedy when she was breaking up with her High School boyfriend. The identity of the boyfriend is unknown. But this became such a popular letter, that it actually sold at auction at Christie’s for $100,000 in 2015.
“I’ve always thought of being in love as 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. I do love you though — and can love you without kissing you every time I see you and I hope you understand that.”
