Or, she leaves him partly out of some twisted desire to see what he would do with himself without her by his side and finds he is functioning fairly well without her. Maybe finding some hot new thing to date. The world did not crumble around him and she decides she really does love him and wants to try again.
I hope that my H would find a hot new thing to date if I left him. I want him to have a hot sex life with or without me. I care for the man after all and I truly wish that everyone on the planet even Rush Limbaugh could have a hot sex life. If my H could better get his groove on with some other woman that would be great. For instance, if he decides that my boundary stating that I am only willing to keep my weight within the healthy guidelines of the surgeon general is bullsh*t and he wants someone really thin, more power to him! All my former feelings of possessiveness are way out the window.
