TD,
I read your thread, and I am about half way into the same situation. I am trying to get my wife to join me in counseling, but we are not talking and I only text her. I bought the course text your ex back, and Fiore recommends texting about past rememberences that you and your wife and kids shared together...something along the lines of: remember when we (insert good memory event). So, do not feel bad about sending your wife that old letter because it is a remember when letter. Stay positive and upbeat...I know it is hard especially when you are getting the crap beat out of you...divorce is like being gutted and left alive...I am trying hard to prevent mine. Thanks.
