Sounds like she "feels" she's under tremendous pressure.
Do you want to be a source of more pressure?

I know you are an emotional wreck over this;
We've all been there. But you've got to get a handle on your emotions and find some peace and strength.

Are you waiting for her to miraculously come home and fix everything to make your pain go away. Don't hold your breath. Fight through the rollercoaster on your own. You can do it.

She want's space? Support her.
She's undecided and unsure, that's not a bad thing.
My W has already filed for D.

Be a source of strength and support for her, not pain and pressure. Get yourself together for the long haul. Understand there are no guarantees.
