I'm a sufferer, was married 23 yrs and then my dear hubby passed away. During our marriage I had an affair, later realized my mistke, quit it and asked forgiveness which was given. My husband died loving me. I miss him so.
I am 58 now and my PTSD was not diagnosed until I was in my mid 40s. It's been a long hard road being treated for it, and I am still under treatment. Meds and therapy... The affair happened shortly after my PTSD diagnosis, an important point I think. I don't know what it would have done to me, if my hubby had been the one to have the affair instead. It is hard to say!
I do understand, especially after a hospital stay, that one can be in a very RAW state emotionally. One feels the need to protect oneself, I did anyway, so I can relate to your wife's needing some distance right now. There were times that I was unable to speak too, I used hand signals with hubby even, as words just did not suffice! I have no way to explain it, but it does happen.
I was molested as a child by a grandfather, so I can relate to that trauma causing all these kinds of thing in your wife. I'd suggest that you let her know you love her, let her know you joined this site and want to support her in any way you can and allow her, her distance for now. Do let her know that you want her in your life, but you are willing to wait. She needs to know these things.
And may God be with you both.
