Ok Hiding,
I have been one that has been diagnosed with PTSD. Unfortunately Complex PTSD is still only just being considered, but really should be more strongly recognized.
I have learned more about PTSD by coming to PC and reading different things on my own. Well, I have to say I am pretty pissed as I displayed many red flags in my search for help through therapists. And I was also very misunderstood and even handed other diagnoses that were not me at all. And those other diagnoses only were based upon my moments of shear anger and confusion and search for validation.
Now, what you are describing within your new relationship where you do have things occur that you feel may result in being denied and blamed by an old relationship IS COMPLEX PTSD. When someone endures certain reactions and treatments or responses over a long period it really does effect the brain. I am really certain of this now as I have tried to overcome very similar abusive, almost bullying for many years and was constantly trying to work around it, point it out and it was always my fault, my imagination. But it wasn't, and it is now very well known and
I am pretty angry.
I know exactly what you are describing and yes, you do have a hard time expecting reactions that were constantly put upon you in your past. You are now hard wired for this so to speak. No, its not you, it is years of being mentally abused.
