There is some good advice given here. I would suggest that you read about something called "mindfulness" stay in today. In my case I was trying to move on and my wife would ask about something about what had happened or where I was at. Many times I just was not ready to talk about had happened. Or I was in a good place and not wanted to be reminded. Of course men handle such things very different than women. "after all we are supposed to be able to protect ourselves" what is forgotten that we as young boys just could not. We were children. Both my wife and I have been in therapy for some years now. I wish you and your husband the best in you journey. It can get better with work and willingness.
it is and has been quite a trip thru life, as last I feel that I am in a better place, it takes work and in my case a wife the was and is forgiveing and helpful. At last a relationship has gone right, messed up three.
