Extremely long, What would you do if this was you?

Your marriage was over a long time ago. Problem is, you refuse to recognize this. How much more pain do you want to take on? Yes, your husband is suffering from PTSD and he doesn't want to seek help for it. You've done all that you could. I'm glad to know that you're in your own apartment. Do not allow this man into your apartment. Unless he's willing to seek mental help, it's better to get on with your life for your son's sake.
