"Let me be clear in that I am not attracted to my wife anymore." That's not surprising.
"She has even said the words I feel like I have grown and you have not." She "feels like"? How has she grown? Who decides what growth is? Must you both grow the at the same rate and in the same direction and see things the same way?
"We are in the same place.. but I "see" much different thought's." What do you mean? You "think" you've grown too?
"Honestly "by the book" it would be a perfect example of LRT." People don't follow the book.
"But I still question if that is really the best choice." All it takes is one of you to make that choice; in which case the other then has no choice - like murder. I would question it even it both of you made the choice - like murder-suicide. They even say its good for the kids.
