I'm not sure I have the best advice here, but if it were me I would stop asking her what she wants. The way she is now it is obvious that she wants to keep moving forward with her plan. The more you keep pushing the further you drive her away.
What would be your 180 in this case? In my case, I wasn't available for my H during my depression, I blocked him out, didn't respond to him or his needs, so I need to be more present. So going dark or dim is not an option at the moment.
In your sitch I would listen to her and be aware of her needs. Maybe not comment about how you feel at the moment.
My two cents.
