I think it will help her put it to rest when she learns the whole story. I could see how she would have felt hurt over that situation without knowing everything you've described in the letter.
I hope you can do as well for the other past offenses.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
