Insight plese

I see a pattern here that has re emerged. I believe it is codependency / fawning..husband a veteran. We watched a war movie tonight based on real events. He has had to follow specific plans. He has insisted I and others do the same in terms of self defense weapons. He believes there will be complete societal breakdown. I exceeded my limits doing this. One time he was trying to instruct me to let him and my dogs- my ESAs - kill someone to save me and that my dogs were just dogs. Citing this one incident - there were others- so it is clear what I experienced. I tried to learn to fire guns with him. I do have a laser. That I am comfortable with. Point is I can never kill someone for our relationship to be focused on his beliefs society will collapse and what he believes I must do to survive is behind my anger and fear. I do not have moral injury. Survivors guilt was an issue and can re emerge. My first deceased husband had diabetes myleodysplastic syndrome and an internet porn addiction - underage. I did everything I could to save him. He died 2012. I got critically ill in 2014 partly or largely trying to safe him..I was on a vent went into cardiopulmonary arrest. Me taking charge of my life and doing what health care providers said after 2014 saved me. I had to tell my husband tonight after we watched this movie I cannot be going through a constant planning and thought process about societal collapse and how to survive according to him. This group and other work I have been doing on myself has clarified this for me. But. I am angry. At my husband. I do not support his beliefs. He may mean the best he says he wants to protect me but it has been very toxic. I would be grateful for any replies. I cannot discuss news polirics with him anymore or anyone else. I could listen briefly but I all I can say is I understand exit the conversation or redirect it. I know my husband needs help for his ptsd we need couples counseling. I tried 5 years ago. He refused

I'm sorry you are going through such a hard time right now. I know of a lot of people who are in that "We must save ourselves, no one is coming to help" mode of thinking right now.
Being a veteran with PTSD can't be easy now with world events going on.
I think you're right that the best you can do is redirect the conversation or remove yourself from it physically. Maybe have an option handy to say "I need to go do laundry now, or I need to the dishes done now, or I have a headache and need to go lie down"?
Just some suggestions. Feel free to disregard what doesn't help. I hope things get better for you.

Thank you. I am doing what you suggest.
