Poet, reading the news isn't helping right now, so maybe it would help to tune it out if you can? It would make me feel worse, too and even less able to do anything.
As for
"I'm spiralling although he's not doing anything"
Right away, to me it seems like there's a whole lot of hurt, despair and hopelessness in that statement.
When I break that down it's you are feeling out of control, maybe hopeless. What matters is you're in pain.
But this is Poet speaking, and she can't have her feelings be valid on their own, can she? So there has to be a conditional clause, and it's "although he isn't doing anything".
That's worth breaking down even more.
For one, you immediately rendered your feelings invalid there. It bears repeating that this is okay, it's what you do because you've probably always done it and habits are hard to break.
Secondly, you seem to feel bad for having them in the first place, and possibly guilt for not feeling good because he's "not doing anything".
I'm going to take a guess and say that is probably not true, it's just how you've come to think about the relationship because it would be unbearable otherwise - so the "good parts" must outweigh the "bad parts".
But this is not thinking holistically, this is you compartmentalizing. That, and detachment/numbness is what disassociation is. This is what you have to do so you don't lose your mind.
So while you may think you owe him feeling good and rewarding him when he "behaves", and feel even worse as a result because you can't although you should, you're not a robot that can switch modes at the press of a button any more than he stops being an abuser* when the act of the assault stops.
A holistic view of relationships would demand that you feel safe in your relationship all the time, no exceptions. Our partners are supposed to enhance our life and we, theirs while not making us depend on their judgment.
Conversely, the assaults or remarks are not isolated incidents, they're part of a cycle that carries over into the "good times" which, I am deeply sorry to say this, prime you for getting abused again.
So to translate, no, it's not that you're "acting up"/"being dramatic"/"being weak/ungrateful" although he is being so "nice"/"helpful"/"calm"/"non-threatening"/"caring", not at all.
It's because you have started letting your feeling surface, stopped repressing them, and they are expanding into places where they are really not welcome - when you are supposed to perform to make him happy. Because maybe you hope that if he's happy, he won't do it again even if he's stressed from work.
I hope you have since started feeling better again. I am sorry for writing this, but I couldn't leave that statement just standing there. Again, it's not at all "wrong" to feel like that, much less unusual, but I feel like examining it critically reveals a lot that needs reframing.
*I know you don't want to think about him this way, you may replace that with "leaves you hurting" which would account for the fact that trauma lingers and twists and turns like a living thing, which it is.
