This is how I'd feel...obviously no concrete evidence, but why not just be a bit more specific?
Assume husband doesn't just communicate by grunts and is reasonably articulate.
And if they're intimate physically and socially the rest of the time, it's not like they're at a "passing ships in the night" relationship stage.
Like FUCK does he not know OP is uncomfortable. He KNOWS, alright.
"I need some deep thinking time on my publication, as I don't in the week"
"I have to be there as the HoD is very aggressive about non-attendance".
Or even invite OP up, a lot of people bring partners onto campus for hang out time. How hard is that?
OP is clearly a level-headed professional herseif (assume she outearns him if she''s City)
It's like he's detected OP is uncomfortable and is intentionally gaslighting her and making her doubt her judgement by obfuscating. Its plausible deniability. It creeps me out.
I've been reading biographies of Ted Hughes over the winter, and honestly that should be required reading for women wanting to learn about how abusers work. They're not all guys in string vests shouting on the street.
Obviously Hughes was an intelligent, attractive guy who could "read" people to manipulate them.
..he'd wind women up by love-bombing them so that they thought there was a great relationship there...then he'd just "disappear" having given just enough information, but also not enough?
So they'd be left looking mad and paranoid and ringing up friends and following him. It was a control mechanism.
Somehow (even without a high salary and children and needy parents) he had multiple women on the go, all of them super intelligent and attractive and often earning more money than him/providing him with home comforts.
It was because he'd beaten down their sense of "what was normal and comfortable and right" and made them think there was something wrong with them.
