I have PTSD also. Have for most of my life, and I am just now understanding why, I keep the ones that I love and care about, at an arms length. Why, I push them out, why I shut down and isolate.....
This may or may not be relevant in your husbands case, but these are just some of the things I am learning about myself....
With most people I know, I can have a mask on, a wall around me for safety that keeps most people at bay. I can have a relationship with them on a casual basis. I can joke, laugh, and maintain myself for the most part.
I have just reunited with my daughter, after 6 years of estrangement......I WANT this relationship so badly that, I know I must totally open up, and what I am finding is extremely painful.....
Our loved ones know us, they have expectations of us, and in a relationship there is an emotional, and physical closeness that one must have.....This is hard for people with PTSD.....
It's hard to open yourself up, it's raw, it hurts, there is fear, shame, guilt, and on some level there is a certain amount of resentment. Well, there is for me anyway....Opening all of this up, is causing a great deal of stress for me, anxiety, flashbacks, and I am fighting to keep my head straight......There are times I just want to say screw it, but I know that I can't....
I'm sorry that you and you child are going through this, and I hope that things get better for you both. Read, and learn as much as you can....It will help.....
