@thesearch My OP became much worse for a bit after the baby came, with the attendant extra mess and lack of time/fucks to give about tidying on my part. I got him to talk about it ONCE, and basically got the impression he was afraid if we let things start to slide, then it would inevitably lead to total chaos and living in filth. He genuinely seemed to think that was the only possible outcome of, say, not emptying the dishwasher the second it was done or leaving some baby blocks on the floor overnight. It was an interesting insight into his mind actually, and made me more sympathetic - even though it is obviously bonkers to think that way, how horrible to feel like that, to feel like there is so much pressure.
I have come to the conclusion I cannot change him, I can only change myself and how I react to him - mainly because we were rowing all the time and I didn't want that in front of our daughter. So I try hard not to react when he starts tidying up pointlessly or fretting excessively over something trivial.
I now thank him if what he's done is actually useful - I used to get upset because he never gave me the chance to do anything and I felt judged and useless so would have a lot of arguments of the "I was going to do that!"/"I'm just helping!" defensive variety.
The other stuff? I ignore. I walk away. I do something else. He knows I don't like it and I want him to be different. For whatever reason he can't or won't change. For me it wasn't enough to end it (thought about it a lot though). The stress of it before was driving me nuts and making me miserable; then i realised that that was just the stress in him infecting me, so I try to shut it out.
I worry sometimes when I see memes about the 'mental load' usually carried by women that I'm just lazy and selfish, and he feels that nothing will get done if he doesn't plan it or sort it. But when he went away with work for a week, daughter and I ticked along fine and the house was fine when he came back. So I think by and large my standards are OK. I just try and draw a line where I won't try to live up to his crazy standards or let him impose them on my daughter, but I won't interfere with him doing whatever mad things he has to do to feel OK as long as it isn't actually impacting on us practically.
But yes, you do have the days you think it shouldn't (and needn't) be this hard.
