Backfired

Rick, I used your recommendation 9 months ago. My wife had left after finding that my addiction to porn was still active. I used the HURT format to draft a letter of remorse to her. I even used some of your verbiage since it seemed to fit our situation well. Over the last few months (we are still separated) the few times we have spoken she has brought up the letter. She says she reads it every two to three weeks to remind her of just how despicable I am as well as for a basis to demand a divorce. I understand that this comes from a place of anger and woundedness, but it really seems to have been counter-productive. Did I miss something?
