Thank you for your insight, it is much appreciated! I had a feeling that it would probably be rare that a WAS changed their mind while still living together. You're definitely right, having constant contact makes it soooo hard to really detach. I struggle with that a lot.
I think since it doesn't seem my Ex won't be moving out any time soon (even though she said she's set on moving out), I will continue GALing, PMAing, and lovingly detach from her. I definitely still have a lot of my own feelings to work through. There are days when I'm not okay, depressed, angry, etc. My ups and downs are definitely less extreme than a few months ago, but I still have more emotional work to do for myself!
