I'm known for being head strong and assertive (I'm actually very sensitive on the inside) no one would think the dynamic of our relationship was actually him in control, no one would believe me.
You don’t know it, but it’s confident women that gaslighting gits get the most kick out of bringing down. You’ve got a vulnerability (“You’re so hard on yourself/such a perfectionist”) that you’ve mostly overcome in your life or turned to your advantage so that people don’t see you that way ... but he knows it’s there, because you trusted him with it, and now he’s working to undermine you. It happens a lot. Sometimes they’re not even conscious of doing it.
Anyway - if he’s a good guy, he’ll back down in the end. If he’s not - well, this is what he’s like to you in the middle of a pandemic when you’re already feeling low and there’s plenty of living space but he can’t compromise without calling you names and sulking...
He's said, right now he doesn't know why we're married. And I'm like meh, piss off and actually fantasising about a nice two bed flat with a plush office on my own.
Too right you should agree with him and tell him to piss off.
You could ask him first what he means by that, though?
What does he think marriage is? Does he think it’s “All that I am I share with you, including my fucking trophies and snowboard and you should be glad of it”? Or does he think it’s “All that I am I share with you, including an equal proportion of the living space and equal respect for each other’s needs, careers and emotional well-being”?
Stay strong.
