"I know now and have discovered in the last few months that I was caught up in old feelings and looking to recreate a past that, at the time of the A, I felt I wanted based on MY poor view of the marriage. "
That's all fine and well, but to be honest, you don't know if you're going to get caught up in those feelings again if your M goes south again.
While it is true that marriages can be saved after an A, it's the fact that she opened her heart to you again and then you broke that trust a second time that's the issue.
In what ways have you exhibited trust? Showing her phone records and emails don't mean anything because you can always have a secret phone and email somewhere else. Many cheaters on here do.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
