I still stand by my earlier posting...then suggest a face to face meeting to discuss what needs to be done and how to move forward and make your marriage/relationship work. Don't put anything in writing because it could very well come back to haunt you.
Verbal communication is the way to go.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
