Help me understand - would heavy drinking + PTSD cause my partner to blackout during an episode in which he was physically violent towards me? He claims he has no recollection of the abuse. Zero. He did not in any way appear to be reliving or reenacting a memory. He was interacting with and raging at me. He claims that PTSD is to blame. I’m having a hard time believing him. FYI we are currently separated and there are legal protections in place for me and kids.
