You are very welcome Apollo. :) I am kind of blown away that my post was so helpful but very glad it was. I think just knowing we aren't alone in this is helpful in itself.
You asked me what my husband and I have done that has helped us. Boy that would be a pretty in depth answer.
Unfortunately PTSD is a roller coaster ride and is not completely curable. This site really helped both my husband and I. PTSD is complicated, especially when caused by childhood abuse, because it can be very difficult to put your finger on the triggers that cause emotional flashbacks. I am learning to notice my body responses so that I know when a flashback is starting. Once I realize I'm having a flashback I try to remember what happened or what I was thinking that kicked it off. CBT and EMDR (which can only be done by a trained specialist, do NOT attempt to do it alone) are helping me to manage my symptoms.
My husband is a very stable person, but this has been tough on him as well. One thing that we had to overcome was his desire to "fix" everything for me. That is a typical male trait, not bad at all, but not helpful in this case. He has had to learn to just listen to me, then accept and validate my feelings. Not an easy task at all, but it really helps. He also knows that there are times when he just has to give me my space. He points out the good things I am doing and the progress I am making. He does not put up with inappropriate actions or words on my part and gently, but firmly points it out when I treat him in a way that is unfair. I am having to learn to understand and have compassion for how my PTSD has affected him too.
As you can see, learning to manage PTSD is very complicated and is done on multiple fronts. Also, what works for one may not work for another. One hard part and something you both need to realize (BIG WARNING!) when your fiance starts dealing with past issues.... it gets harder before it gets better. Reading the articles on the home page will help you both to understand PTSD better. Reading the individual posts here by sufferers will bring up many emotions for your fiance and quite possibly memories that she has either suppressed or were completely block before. It's not easy to deal with all of that and takes a tremendous amount of courage to do so. Your fiance is strong and a fighter/survivor or she wouldn't still be alive and sane. She can do it, but please, please realize that it is a tough road while digging it all up.
I would recommend that you visit the carers section on the forum. You will need to take care of yourself in order to be able to help her. The carers here can help give you support and advice that you will find invaluable.
(((HUGS))) to you both.
