Lincoln writes to his friend, Joshua F. Speed, of Louisville, Kentucky. Lincoln reveals his discontent since he ended the relationship with Mary Todd over a year ago. He writes, "Since then, it seems to me, I should have been entirely happy, but for the never-absent idea, that there is one still unhappy whom I have contributed to make so. That still kills my soul. I can not but reproach myself, for even wishing to be happy while she is otherwise."Abraham Lincoln to Joshua F. Speed, 27 March 1842, CW, 1:282-83.
