Late to the game

[Free]

I'm back. Between some work trips, the holidays, and an emergency surgery, I was out of commission for a while.
Here is the latest update.
We are still together at home, but I no longer exist in W's world in any way. There is no talking to her. If I try, she pretends to not hear it. If all 5 of us are at home, she puts 4 dinner plates on the table. I needed someone to pick me up from the hospital, she never offered or asked. I had to call a friend to get me. When I made it home from the hospital, she never spoke a word. Never asked how I was or what the Dr's said.
I confirmed that she has consulted with a L, but has not filed. I also confirmed that there is no one else involved on her side. By all accounts, she just wants to be alone. More importantly, she just wants to get away from me.
I know she hears me when I speak, so I remain cordial whether we are alone or with family. I do not expect a response in any way.
We are both still seeing therapist separately.
I've read through a million sitch's on here, and I've never seen a situation where the LBH is just ignored. WAW's are cold, unemotional and sometimes angry from what I see. My W has taken it to a new level.
She obviously wants me away from her, so I get out and do things as much as possible to keep things from getting worse. She does little to nothing outside of work, so she is home often.
So, should I continue to be cordial? It's only become worse over time, so maybe I shouldn't be? I don't know how to proceed with this.
I still love her and do not want to get divorced.
Thoughts??
