My husband is a horrible communicator, even when PTSD isn't roaring it's ugly head but when it does, it's even worse. Her a quiet guy my nature and that doesn't help. It's so hard when there is nothing you can do to save them from the fight within. It's hard being ignored, feeling isolated from his heart, thinking you aren't heard, or your feelings don't matter. Wanting so desperately to take the pain away (yours and his), feeling hopeless and useless. It can drive you insane You question everything you've said and done and you secretly wonder if you are his trigger.
It's unfair. It's hard. It's down right heart wrenching. PTSD claims it's victims when and where it wants to and we have no say.
Getting therapy for yourself helps tremendously. Having a support system helps to. My family doesn't understand so I keep them out of it. I go to people that support me, people that get it. We tend to isolate ourselves when our partner isolates. Don't do that. I walk, listen to upbeat music, pray, find things to laugh about. If my husband sees me struggling when he's having an episode, he goes deeper within himself. For years I thought it was not caring, purposely pushing me away or him just being an ass. But I have learned that when he sees me struggling because of his behavior, he feels guilt, self loathing and wants to get out of the marriage to end MY pain, not his.
So I would suggest to send him some hysterical memes (only a few). Be upbeat, positive and take your emotional hut to others than can handle it but not to him. Don't talk to him about the relationship . . . Not now. He probably thinks he doesn't deserve you right now. Show him that you are strong and his PTSD won't define your self worth or your positivity.
One thing that's hard to understand is that when the are in the numbing stage . . . They KNOW they love you but they can not FEEL that live towards You, themselves or anyone else. It's a defence mechanism to protect themselves. When you understand PTSD more and more you find that you won't take it so personally. My prayers to you because I've been where you are and I know how hurtful and confusing this is but you seem like a wise and strong women. You got this. Be patient but most of all be happy!
