Hi JD,
My take on this is to just let her be, for the moment. This is obviously a highly emotive issue for both of you and if your wife has said that she doesn't think you know her any more, then to me, this is a big danger signal.
My husband was mentally and psychologically abusive and very controlling, but not obviously.....no one else but me and our 2 sons ever saw this. One of the worst things he ever did to me was to force me to reveal the sexual abuse I went through as a child, it was something that belonged to me, at the deepest most basic level, it was mine to know and didn't belong to him. He had no right to it and no right to force it from me..........he did it in a relentless caring way, pressure to reveal, pressure to share over many months until I caved. I was receiving counselling at the time and was off work because I was going through a mental breakdown........that was where, in my mind, my marriage ended, the final trust breached.
Please don't think I'm comparing you to him.......I'm not, but sometimes we can get to a state where we CANNOT share, we need to retreat to understand ourselves to wonder what is happening to us, to find out who we are, to work out if we even like ourselves let alone even begin to love ourselves, we grieve for our former selves, our former lives, the anger and deep sadness is all encompassing, often there is not room for anything else........we are in crisis, we need to be in our head on our own.
Recently I been in my own period of self reflection after more health issues beside PsA landed in my lap. This has been a test for my new man (coming up to 3 years) he amazed me........I warned him I was on shaky ground, but that was it I didn't know what else to say.........some evenings I don't think we spoke, but its wasn't bad silence.........he gave me space, he didn't ask me what was wrong, but told me he loved me and if I wanted to talk it was ok, if I didn't it was ok he just carried on as normal and was himself..........no pressure. I can't tell you how that made me feel........I could work through it on my own and know his support and love was there and I love him all the more for it..........I didn't have to ask, I didn't have to tell him what was needed he just followed his instinct and let me be. His answer when I asked him a couple of days ago how he knew what to do.........."you are such a strong person, you have survived so much, you know what's best for you. I wanted to take it from you but knew I couldn't begin to understand how to, so I wanted to just be there in the background for you, and love you with out pressure"
He's definitely a keeper.
I don't know if this helps at all JD, but just thought Id let you know how the inside of my mind works when I'm in crisis, I CAN'T let anyone in I have to do it myself, get there myself and yes that sometimes means sexually.
