It sounds like you are doing all you. As a survior I can tell it is and will be a rough road for him. It took me almost three years to let it all out and even then I know there are pieces that I just do not or can not let out. At some point it may help for you to meet with his T. This would help you for yourself and to understand his process better. My wife was there when I could talk about it and did not pressure me. What a wise women and wife. I am trying to speak to what we have done,which has worked, Keep in mind each man and his experiance is differant, so the path to some normanize is differant. Just tell him of your love and you are there if he wishes to talk, in the mean time take care of yourself,read, see a T if you can, our thoughts and best wishes are you.
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.
