Yes. It's part of the behaviour they use to wear you down and drive you mad.
It reminds me of a friend I had who came to stay with his girlfriend at mine (I lived in the city so often mates from afar would use my place as a base when they wanted to visit it). He would have such strange, constant, round about arguments like this with her. Had never seen him do it to anyone else and I was young so just assumed it was what they were into. But then a year he had a new gf and he was the same with her and I could tell she was frustrated by it.
Looking back I realise he was likely mindfucking them both to the point of exhaustion.
I had a narcissist of my own briefly like that. Would d o and say things geared to exhaust me. I won't get into the list but yes, some of that lot are absolutely like that.
At the end of the day, it's abuse designed to rob you of your own sanity. I can't think of anything more insidious really.
I hope you get away from him. Amd remember, you don't have to prove or justify why you are leaving him. Not to anyone. Not to him or his ass kissing family. Even his sister sounds like a simular creature to him. Using putting him on a pedestal to make you feel 'unworthy'. Standard dysfunctional narcissist bullshit.
Just 'I'm not happy in this marriage anymore'. You don't need to explain. He knows why. If he's going to be a pain in the divorce anyway you can even just be honest and zay 'because you're a fucking douchenozzle so I'm out. Clear enough for you?'. Just never, ever, eveeeeeer use the word narcissist when talking to them.
Never let them know you know what they are. If you use this word they will flip it and tell you YOU are the narcissist. They'll tell everyone you know too. I mean, not that it matters if these people are decent and know you as they'll not believe him. But still it's not nice to stand up to an abuser and have him tell everyone you are the one who did the things HE did.
So keep it to simple statements 'I'm not happy anymore so I'm done'. Don't explain why. 'You owe me an explaination?' 'No, no I don't. My solicitor will be in touch with the particulars' (or 'Ok, you're an arsehole and I'd rather not spend the rest of my life with you so I'm out. There you go, that's why').
