R, understandably you are attached to your wife and your marriage, we all are. I read this and connected with it, maybe it will help you see it from a different angle. This is an example to illustrate attachment that I love:
"In the South of India, people used to catch monkeys in a very special way. Actually they let monkeys catch themselves. What they did is cutting a small hole in a coconut, just large enough for a monkey to put its hand in. Next, you fix the coconut to a tree, and fill it with a sweet. The monkey smells the sweet, squeezes its hand into the coconut, grabs the sweet and .... finds that the fist does not fit through the hole. Now the trick is, that the last thing the monkey will think of is to let go of the sweet; and it holds itself prisoner. Nothing could be easier for a human being who comes and catches it."
This is what we do to ourselves after BD. Please consider letting go to free yourself. The sweet will still be there if you let go.
