Behavior changes?

I've noticed some changes these last few days. I guess if the moods are changing so will the behaviors.

So she's using the space agreement we came to, which is if she closes the door she's to be left alone.
She's using it..... which I think is a success. I want her to have space so she can de-stress, collect her thoughts, and hopefully slowly work thru this. She came home in a terrible mood last night after fighting with her work friends and kept the door closed all night.

Something else I've noticed is she is always covered now, and if I'm walking by (I'm not stopping to stare at her or anything) she'll grab stuff to cover her body (such as when we're getting ready/dressed for work).
It is normal to become a stranger to your spouse (in their MLC eyes)?

A positive: She cleaned a little last night, I found out when I had my midnight protein shake. She hasn't done any of that since this started.
This morning I was sure to thank her for that and tell her I appreciated it. Seemed like she appreciated that I noticed and called it out. I admit I took it for granted before, I'm 180'ing that.
