Hi Auburngirl
I was married for 5 years when I went through my trauma. My husband seen the old me, the trauma, and the new me. He was there for the first few months after, and for the PTSD diagnosis, but had to leave before a year was out.
If there is anything I can pass on to you, it is to be honest. I wasnt, I didnt share anything, and it really makes any space between you bigger. I dont mean you spill all your emotions, or even tell him what happened until you trust him, but he does need to know what he is getting into. For example, I have this speech I gave my boyfriend now about having issues from a past trauma, how everybody reacts differently but I struggle with.... It could have made 'em run, but it helped build the trust and acceptance between us.
As far as literature, the best I have seen is right here in this forum. It takes a while to get through it all, but it is worth it. I havent actually given my boyfriend any of that, I was worried it would confuse my issue with general issues of PTSD. But he has come to see my T, a couple months after we met, and my T was able to explain my patterns and help us find a way to communicate those. That was a GREAT experience for both of us. (he was hesitant to go, scared of 'head shrinks', but admits it helped us)
