So the advice is not to tell her, why I moved her things out of the master bath/bedroom?
She will know why. That doesn't mean she won't react to it. I suggest you have a statement ready, just in case. Something like, "If we aren't going to have a respectable M, then I see no point in sharing the MBR", or "I have decided not to share my bed with a W who doesn't respect me".
More than likely, she'll have some b.s. story.....and expect you to buy it. At this point, she must see you as a man who is rejecting her crumbs. Don't start telling her what you want, b/c she already knows. The less you open your mouth, the better. When she gets serious enough......she'll know what to do. Currently, she's playing you like a fool. All that bait she dangled at you was nothing but fool's bait. She will continue playing you, until you decide you are done with it.
I don't know your W, and she may come at you hard. I've seen some women put their things back in the MBR, and if the H tries to interfere, she calls the cops. You have to think beyond the action you've taken. There may or may not be any backlash. If she moves her things back into the MBR, so be it. You don't want it to lead to some type of domestic call to the cops, b/c it doesn't usually go in the man's favor. Be smart.
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!
