No worries.
I'm sorry it was a bit full-on.
Dissociation, PTSD dissociation to me, is a really full-on experience.
Perhaps it's a really full-on lack of experience?
Emotional numbing/checking out is too, just differently so.
I can automate and robot-ify myself really well, remember everything and get a lot of shit done when I'm upset. I planned a funeral and a wake, made 29 phonecalls in 2 hours, looked after everyone, until five years later, after my best friend died, because there was shit that needed doing.
The only tears I cried were after I was putting her sax in it's case, after I'd played her fav song on it at her funeral then there were people who needed me.
That might be what your husband is doing.
Numbing it out is often mistaken as a sign that the emotion is so minor, the person decides to deal with it later. It can feel like the person has decided it's less important than whatever they've got going on in their head. It's like clicking "not now" on a software update, or so it seems.
To me, it's kinda the opposite. It's more like, I could be emotional about this, but if I do that, I'm gonna break down completely. I can't even let a little crack happen, because if I do, I'm gonna completely lose it, and there are people that need me to hold it together. My thought process was that it was better to be numb and avoid being emotional for other people's sakes. I thought I was being generous, not selfish.
I didn't know what would happen if I fell apart, and I couldn't guarantee the people I loved would be looked after. I couldn't guarantee I would come out of the emotion alive, even.
If I let myself do even a little bit, my floodgates would burst, and there was no telling what would happen next. I had stuff to do, and I couldn't afford to.
(I use a lot of "i" statements, because I don't want to make assumptions. I don't know what's going on, but I'm trying to help, hopefully by sharing relevant stuff.)
I cared about the people in my life very much. I loved and love them. I thought I was doing the best thing by them.
If your husband is numbing you out, not dealing, not engaging etc, I know this sounds weird, but it's probably a sign that he cares about you very much.
I couldn't bear to let my loved ones know, even at that time. I have unrelated PTSD, and that was after the PTSD stuff happened.
Here for you, mate.
