Wow hope, that thought never crossed my mind. What if she doesn't know?
And yes, MT, one of the most hurtful things for me was finding an actual love letter that OW2 gave H. I knew, had known for 2 years and didn't find the letter til after it was over but it broke my heart into about a billion pieces. So definately be prepared for that.
If you focus on the past, you ruin the future. You can only live for today.
