Good letter Jeff. It may be something she would reflect back on if your marriage does fail. Just realize that there are no magic words that are going to change someones mind right away to start loving you again. Keep the expectations low.
The only thing I might have changed is to try to show a bit more husbandly leadership. At the end, you kind of leave it up to her to decide the path - reconciliation (what you want) or separation/divorce. You do point out that the status quo is not working, but you dont say what you will do if she tries to stay with the status quo.
Maybe it would do more harm than good if you did try to be too strong by saying if the status quo continues that you will be forced to file for a separation or a divorce. It may be best to hold that off for any subsequent letters depending upon how she reacts to this one. Give her plenty of time to absorb and think about this one.
I hope there is some movement in your frustrating situation soon. You so deserve the love which comes from a good marriage.
