You have been slipping with using the renter guideline. Like when you were texting her the other night. You really push her away with that kind of behavior.
If she was a renter, you would not have your clothes in her room, and you certainly would not use her bathroom. If I had been your WAW, I would have thought you wanted me to hear you, so that I'd know when you got home.
Don't you think if you are going to sleep in another room, it is time to get your things out of the room she is in? Then there will be no reason to enter.
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!
