Maybe an ideal opportunity to focus on activities for you, especially if she is calling. Maybe not accept every invite as you have suggested in the past?
Two. Right now she is still not divorced in her mind if she has access to the house and seems to act as she pleases. You may want to set boundaries, talk about respect for each others space, you certainly would not come and go and take things from her house. How would she react if you did?
BUT and you know this, be prepare for NEGATIVE reaction when you set boundaries and most likely she will retreat hard.
But continue to focus on those activities for you.
It sucks, we are doing all this self-evaluation, analysis, figuring out how to act and what to say and the WAS has already left the R and is moving on with a life outside of ours and yet . . .
