Apparently he is divorcing her because she didn't defend his honor? Gawker is covering it but...eh.
"...and I am disappointed that she was advised to make no public comment to explain that I abhor violence of any kind against women, and have never abused her physically in any way."
This comment on Gawker includes an image of the whole letter which is disgusting, but I don't know where (s)he got it.
It makes me sick - the dissonance.
Classic fucking narcissist, making this about him and how it affects him without thinking twice about the implications and consequences of his actions. While he admits they have become estranged, he cites the reason to divorce her as her unwillingness to defend him (as well as his being "disappointing" to her), not the fact that they have fights that get physical.
He is unwilling or unable to understand that you can't do what you want to get what you want - another narcissist move. The "but she wouldn't listen to me so I just put my hands on her throat to prove a point" defense is so ridiculous - SHE DOESN'T HAVE TO LISTEN TO YOU. You don't have to listen to her either. Not a recipe for a great relationship but you don't MAKE SOMEONE do these things. You can't.
And of course, still no admitting that what he did was out of line - pressure or no pressure applied to her neck.
I'm glad she's getting out, and I'm glad she's not making comments. She needs to deal with this in her own time, in her own way, and protect her children. I can't imagine what a tough moment this is for her.
