@SarahAndQuack I'm not applying one standard to her and one to him, and this isn't a thread about decor preferences. The context of the OP's decision is that the house is going to be valued with a view to sale, then presumably put on the market.
But you are ignoring the fact that she says she decided to book the valuation. Before that, they had only been discussing moving. Personally, I would be annoyed if my partner booked a valuation, and then decided to move my stuff on the grounds that it was needed for a valuation and/or a sale. It is perfectly possible he wasn't even aware a valuation booking had been arranged.
She suggested the door a long time ago. No door was put up. Many couples (not all but many) divide tasks outside of normal chores between DIY/men and secretarial/women. It's very possible there was an assumption that fitting a door would be his task. We don't know if he flat out refused to put up a door, or if it was a conversation that just fizzled out, or if the OP decided not to nag him about the door after he had agreed to get a door put up. If the door wasn't put up, then I suspect this was because he didn't want a door put there, and stalling on it and just never getting round to it was his way of saying no.
Ah, so you're saying it's ok she's sexist, and it was his job? No, I'm sorry, I disagree. We don't know what happened. It is not ok to presume that he even wanted the door to be put up - and why on earth should one partner in a relationship be entitled to lay down the law about this?! Are you really trying to say that one person in a relationship is not allowed to say no? Because that's really not a healthy relationship, in my view.
I saw - and, IIRC, replied to - Santi's speculations. I do get where she and you are coming from, but without the OP's responses, all we're all doing is guessing. I don't really follow why you think her post is any more authoritative than mine? We've both got experience of being in a relationship and disagreeing over chores ... so have most people.
I absolutely agree it is possible he is awful. He's clearly at fault for yelling at her, and we already know that. I really respect your perspective (on this thread and in general), but I just can't bring myself to see that the wider issue is so obviously black-and-white.
