I would like to challenge your thinking on the word PRO darknes. M is a decision not taken lightly, a vow between you and your W before God. A vow to commit to only one person until you die.
Your PRO is condoning infidelity. You're saying that even if my WW sleeps with the entire soccer team because I pushed her away, then I must learn to accept it and ultimately we need to find ourselves and each other. This goes against the monogamous institution that we all signed up for and once believed in, when we got married.
What chapter 1 of the DR book is saying, is that we should allow infidelity and accept polygamy in M. These are simple blips in the pursuit of happiness.
I disagree. M for me is a choice, a choice to be together. My WW has made her wrong choice. I need to make the right one now.
Just cos things are going right, doesn't mean that they were always wrong.
