There's a woman I worked with who could find fault in anything her husband did
The way he loaded the dishwasher. The way he spoke to her parents. The way he breathed, probably. She came to me convinced the problem was him.

Took exactly one session before something cracked open.
She'd spent fifteen years being ashamed of where she came from. Her family. Her accent. The suburb she grew up in. She'd built a very controlled life to cover it. And her husband, who was relaxed and imperfect and entirely unbothered by what people thought, reminded her of everything she was trying to escape in herself.
She wasn't judging him. She was judging herself. As her mom judged her.
That's how shame works. It disguises itself as standards. As taste. As knowing better. You think you're being discerning. You're actually being cornered by fear of judgement. So you judge.
I've never met a genuinely at-peace person who was also relentlessly critical of the people around them. Not ever, not once. The math doesn't work.
When you're settled in yourself, other people's imperfections are just noise. When you're not, they're evidence.
If you find yourself cataloguing everything he does wrong, that list is worth examining. It's telling you something about what's unresolved in you, not what's broken in him (note; not always).
The hard thing about this is that it requires you to stop outsourcing the discomfort.
He's not the reason you feel the way you feel. He's just the nearest wall.
