Yes, I feel your frustration. I'm very sorry to hear about the developments of your sitch. A part of me thinks that yes, living separately might very well be the answer - you know, giving her space to see what it feels like without you. In the meantime, maybe there is a way you can begin to enforce that while you are still at home do you think?
Sleep in separate spaces for example. Consider asking her to sleep on the couch if there is no spare private bedroom, because you need to your space and want to go LRT.
I remember you asking for advice on how to jumpstart something. Things have been at this status quo for a while. There's also a standoff feeling as well - maybe a bit of cake eating from her end?
