I'll go one step further, especially earlier on in sitches, and that is that these are cycles, not necessarily stages. Stages are things you typically move through and from to another stage. What you are feeling, I believe is cyclical. LBSs cycle between wanting their WASs back at all costs, to wanting to tell them to hit the bricks, to wanting to file for D and being done, to not caring (apathy). And you will continue to cycle through these. The good news is that this cycle trends towards the wanting to move on and apathy over time.
I know in my own sitch, I would cycle through this. Even when my W started to show signs of moving towards R, I would cycle through these cycles. I remember posting a post very similar to your latest in my own thread. That is why it is always good to feel and understand what you are feeling, but give it some time to make sure it is real before acting on it. There are LBSs here that would feel like this, rush out and file for D, and then regret that decision.
