TL;DR Version. Shes home. She stayed in spare bedroom with no arguments. Asked about showering in master, I told her shower,sleep,etc wherever you want, you live here too and your choice.
I thought she had been detaching as she'd made comments of being "numb" towards me. not angry, not sad, not happy, not nothing, but this was completely incorrect. Everything I say to her, is received with extreme criticism, rejection, and some form of frustrated/angry response.
I stay calm, nice, caring, try to validate (when possible), and she doesn't seem to soften at all right now, and that's fine, not expected. Her unpredictable out-lashings of now, are becoming more reminiscent of her wild antics of the past, and is really only making the detachment process for me even easier.
