Just to keep it straight, when I'm talking about the C pushing her too far and maybe more being required than your W was ready to give at the time.....apparently, that is how she felt toward hanging onto her "privacy". However, the C should have explained very carefully how the M can't survive without honesty and openness after betrayal has taken place. Perhaps the C tried very hard to do that very thing, yet your W couldn't turn lose of "something".....pride, embarrassment, stubbornness, the OM, the excitement and secrecy, or revealing her sources.....whatever.
Has she ever been the type to withhold information from you? I know some women do keep some things from their H....thinking they are preventing other problems occurring. If she has been the type person who has to have her space & privacy ever since you've known her....then it's more likely she'll think she can continue after she's betrayed her H.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
