Hi OP. It makes sense that this keeps looping, what you’re describing is a really common miscommunication pattern, not a “who’s right/wrong” problem.
What’s happening underneath is,
you’re both hearing words, but filtering them through completely different internal states.
You’re in “split attention” (working, baby in the background, already stretched), so your brain is trying to process quickly and fill in gaps. That’s why you said yes before fully hearing, not carelessness, just cognitive overload.
He, on the other hand, is likely already carrying a sensitivity around feeling rejected or not prioritised (especially with the intimacy piece). So when you say “what?” or correct him, his brain doesn’t hear “I didn’t catch that”, it hears “you’re wrong / not being listened to / not important.”
So the argument isn’t really about what was actually said.
It becomes:
You: “I didn’t hear you properly”
Him: “You’re always saying I’m wrong”
Two completely different conversations happening at the same time.
So because neither of you feels understood, you both push harder, you explain, he defends, and it escalates.
Something as simple as: “Wait, I think I misunderstood, do you mind repeating that,” could interrupt the pattern before it turns into a blame cycle and get you back on track to what you were actually trying to discuss.
