Good for you interms of detachment. It is a great place to be. I feel like I am in a great spot now as well.
The separation in my case was for the better. I use the time to really work on myself while letting my WW experience exactly what life is like without me. I have seen changes in her lately. Interactions were very limited between us, especially for the first 4-5 months but it kept me in a pretty good mental state.
I wish I had some advice on how to handle the remaining time before she moves out. For me, that happened very quickly, within about 3 weeks of BD. I pretty much avoided her as much as I could during that time, ignored most of her calls. I remember how 'confused' she was right before she left but she still left anyway. I think the way I handled it made it easier when she did leave.
Sorry I missed your other posts, I do look out for your thread. Stay strong...
