This is the key question. I think your W calls her room, "her room."
So, she considers you two to have separate bedrooms. By denying this, you are both giving her less space than she is showing she wants and you are demonstrating that you are more into the R than she is.
That being said, it sounds like you are just hopping back on your treadmill. Things improve somewhat. You take no real action. You get pissed that there is no real change. And then you start stomping around, acting out, etc...
