When my ex and I argued, I would get so wired up, I would start hyperventilating, stuttering and saying the darnest things, that in some corner of my mind I would be thinking "why am I saying this?!!" but I would keep going because the rest of my mind was like, this is what needs to be said and heard!! It would be extra frustrating / infuriating when he would tell me he can't talk to me when I'm being irrational.
One good thing he did, though I absolutely hated it at the time, was to tell me to stop, breathe and let's walk away from it for the moment. Sometimes, he would have to physically leave the house, because that was the only way. And then I would be both angry, and scared that he was just never going to come back, which didn't make sense...he had to come back eventually. But still...once an hour or two passed, I was sure of it he was already on a plane halfway across the world.
Mind you, it didn't even have to be a crazy loud vicious argument...it could be something so super simple, we're not yelling at each other or anything...I was just riled up and saying (what I realized later to be) ridiculous things in the heat of the moment. And I'd just keep going...and going...and going...
We dated around 10yrs ago, we didn't talk much for awhile, and just a few months ago after my diagnosis I started working for him again. I told him about my PTSD, and explained a bit what I was going through.. I realized he did a bit of research on his own when a few weeks ago, he told me that from what he's read and understands, it explains *a lot* of what happened during our relationship.
And here I was thinking...I was totally fine all that time! But he saw it and would say the same thing your husband is..that it was like talking to a completely different person. The way I would react and the things I would say, didn't seem like me at all. It's funny in a way, that I never really saw that for myself. And putting it out there now, realize I wasn't keeping it together all these years as well as I thought I was.
