Challenge accepted:
This perfect girl sees you for the ugly person you are and begins having many different affairs. However, she does not break it off because she wants you to keep supporting her financially. Eventually though, she runs you dry, and spends more and more time with her various lovers. At first you try to ignore the signs despite your friends and family telling you otherwise, you act like nothing's wrong and your relationship is perfect. After years of this though, you can no longer ignore the pain of her betrayal, so you break it off and rent a motel room because you cannot return to the house which reminds you of her. You then see the only medicine for your pain is to end your life, and you attempt to do it several times, but each time, your curse of immortality keeps you alive. Realizing that you are now forced to like the rest of your immortal life in agony and alone, you exile yourself to where no one can hurt you like she did, never to be seen again.
Check mate.
I wish people came up with better wishes to corrupt, this is too easy.
