I told my husband about this site, and also showed him some threads that I thought would give him a so called "light bulb" moment. It has opened his eyes a fair bit, and so far this forum has been a helpful tool in our marriage and in his effort to continue to get better. I was worried as well that he would hate me putting his issue out in the open, on the internet with strangers, but he was quite receptive.
I also told him that it helped me to see that I am not alone in the battle that is his PTSD and that I could gain support by carers and sufferers alike. Once he saw that this isnt a site bashing husbands or putting anyone down, he actually read a few threads. Especially the one on verbal abuse. He cried after reading it, because I honestly think some of the stories really equated to how he felt and why he did it.
I'm not sure if he comes on here now, by himself, but I dont need to know, because I know this is a "safe place" for him to share his feelings :)
