And that's the way to handle still living with him - gray rock and only have necessary communications.
The look of hatred used to scare me and freak me out. I even told my ex you treat me like you hate me and like I'm the enemy. I said that more than a few times. The word salad, the circular conversations, and the gaslighting all made me insane.
I'm glad you're not physical/having sex with him. That does make it a bit easier.
And he got physical with you? Did you call the police?
