I am inclined to agree w/Vapo. This is a broken bridge that only your w and daughters can rebuild. I know that you are curious to read what she has to say...but I do not think it's advisable to get between the two parties. Give the letter to the girls and let them decide what they want to do. They may leave it on the counter or they may toss it out...but that's not for you to decide. Also, once it's in the trash, leave it there because it's not written to you...but to the girls.
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.
