Omg, that reminds me of my covert narc ex, who would go silent during phone calls. So I wouldn't say anything either, and we'd both be sitting there on the phone not saying anything! I'm over half a century old, and I've never had anyone do that before or since. He was such a freakshow.
Once, we had an argument and then I went to have shower, as it was the morning. In the shower, I heard these deep, disturbing thumps/thuds. They were really loud. I genuinely thought that someone was messing about on the roof - top floor flat linked to other buildings.
Turns out it was him, doing what he called "bunny hops" on the floor.
So yeah, turned out that when he was upset, he thumped like a rabbit does when they're annoyed.
I'm just sad I didn't see it!
Edit: And also similar to the post above, mine would expect me to see through walls. He would disappear while we were out shopping and I'd gone to the loo or something, and then he'd get annoyed that I didn't know he was waiting in the stairwell. say, me having searched the shop floor.
