Navy Spouce,
I know you wonder about whether it is the PTSD or some other cause. I hate to say this, but just from what little you said I think it's probably the PTSD. It sounds like his trauma is really recent. He's probably having all kinds of emotions right now. As a guy he isn't able to express it so it is coming out in his behavior--which is unpleasant.
All I can say is, and I feel bad saying this but you probably can't take it personally although I know I know it feels very personal. If he loved you before--he still does.
Pushing family away is pretty "normal" as you will see from reading this forum. Sad but true.
I hate to say this also, but the PTSD isn't something he is really choosing. I'd say he is in a heap of emotional turmoil and pain. Just think, when my husband went to the Vietnam wall he broke down and cried. He then admitted his survivors guilt. This was 35 years prior and it was still eating him up inside.
So with your husband I think he probably doesn't understand his feelings, and isn't able at present to really be there for you at all. Just imagine he came home with an actual brain injury and he can't walk and talk yet. In this case you could see the bandages around his head. He may need round the clock care, but it would be easier because it is tangible. Even if you had to feed him and do all these tasks for him.
Well, he does have an injury it's just on the inside of his brain.
It would be easier if it was an injury we could see physically. However, it is just as deep and profound. When he heals a little he will probably still have limitations and scars.
I know it's super hard because you love him and I know you just need some support and reassurance from him.
None of this is easy, but I think it's really good that you are having him in your life. You do have some contact with each other. That's so good for your girls.
Is he getting any kind of therapy? I think you will be helped the more you learn also about the disease. It is really commendable that you are really hanging in there and doing what you can. I'm truly sorry it is such a hard thing to go through. How long had you been married?
