@jphillips90 - wow, living in the town where my trauma happened would break me down. It's hard for people who don't have PTSD to understand it. We all know that, but yet those words like "just get over it" - THEY STING. If only it was that easy!
Over time, I have learned that people say this for much the reasons you describe - they have their own acceptance, grief, and recovery process.
It sounds like if the marriage is at the point where it's either he does a 35 minute commute, or he lives with you while you suffer in PTSD hell - I don't think that this will be solved by him just reading a book. Nor do I think your symptoms will be solved by you divorcing him and co=parenting with him. He is still probably going to be in that town and you are going to have to travel back to the town.
I think you two need to work on communication first and foremost so that he really gets have serious this is for you. I imagine all his comments would make this nearly impossible, but if you have a good therapist, they should be able to help you work on this.
Therapy session may benefit other spouse's greatly ( and maybe at some point he would want to do it) but I think it would be too pushy. If he went it would be to apease me...kinda defeats the whole damn purpose. I go to my reg sessions for me...no need to bring him for my benefit. I really just want to offer it the book as planned and if after some time has passed...if he reads it and it helps great, if he doesn't then I think it would best for all of us to focus on co-parenting and seperating smoothly. I want to see my family happy at the end of the day...however that may be. We will see.
Something about how you write feels like it is really hard for you to stand up for what you need and express clear bright boundaries - which makes sense, trauma makes it hard to do these things. Planning on leaving a book on PTSD lying around the house hoping that he will read it, while also refusing to invite him to a therapy session because it would be too pushy, and yet talking about separating and co-parenting, which in-directly suggests divorce... it's kind of a mixed message. Putting your decision to divorce or not on the issue of if he will read a book you happen to leave around the house is not fair to him, OR YOU. It also puts all the marriage on him changing, when you can really only change you. (Again, I think he is being a jerk and that he does need to wake up and change.)
When I was struggling with my family and friends not understanding PTSD, I read the book " Nonviolent Communication: A Language of Life " - and it helped me in huge ways to talk to them differently. My therapist gave me the book to help me talk to family who said much the same things as you. I was not using "violent" communication before - don't let the name throw you off. It helps people see our perspective in whole new ways. It helped me find a way to be more assertive that wasn't so hard for me.
And after you are done reading it, then maybe you can share it with him too.
