Hey, Rune,
Well, sounds like she's had a serious trigger, and with that I can relate with her. I had my trigger a year ago May, and it's been a bumpy bumpy road since. However, if she has a good therapist, there is hope.
However, some of the issues you mentioned seem older than a few months. But since they went undealt with before the trigger, I think you're going to have to wait it out, and deal with them later when she gets closer to healing/processing.
My therapist says the fastest she's seen someone come through the worst of a PTSD/triggered now-dealing-with-stuff is about 18 months. Not to take hope away from you, but actually to give it-- it takes time, but there is reason to think that although PTSD doesn't go away, it does get to where it can be managed.
I've gone through phases of how much I disclosed to my husband, and honestly, I think I disclosed too much, or maybe too much too soon -- well, I don't know, but it's really hard. It's hard to have this stuff in your head, in your past, and to lay yourself bare to a therapist, and also maybe to your husband, or maybe not. I know this doesn't help you, but I guess what I'm trying to say is it's not a question of love -- there are so many emotions and pain and fears and exposure and vulnerability -- if she's closed in on herself right now it's because she's probably terrified to be anything but. That doesn't mean it's forever, she's still early in the counseling if she only got diagnosed 2 months ago. I hope she's with a good trauma therapist, and perhaps ends up considering some medication support as well. I resisted a long time, personally.
Just to give you an idea of my timeline -- not to say it will be hers, but maybe it will help to know -- my event was in May 2010, I switched to a trauma therapist 8/31/10, so exactly a year ago yesterday, and it wasn't until March that I really opened up to my husband about all of it (which I still don't know if that was a mistake or not). March is also when I agreed to try medication to help also.
Things still are hard, and here it is a year later and I still feel in some ways in the beginning stages. I don't know the answers, just sorry it's hard for you, as well. And recognize that it's hard with absolutely nothing you can do to influence the timing or outcome. That has to suck.
