My took the plunge and sent my ex a closure text. Here it is...
This is closure for me not for you so no affirmation needed. Even before I broke up with you I know you were no longer vested in us. I do want to thank you for showing me the error of my ways. Now, I've got new purpose and I will learn from this experience and know what not to bring into my next relationship, unrealistic expectations. Thank you for giving me the courage to walk away.... - Forever Lost
