I think one needs to analyse exactly why your partner acts like he does.
Some people are just lazy slobs, dirty washing on the floor, expecting people to look after them, cannot see why they should change
Others it seems to be some ingrained instinct in them. Even DH's mother used to say of him 'born in a barn, if I didn't know better'. He quite simply never puts anything away, no door, drawer or cupboard shut. Things carefully left on the worktop above or below the cupboard they should be in - and this is the difference, he doesn't leave clothes or towels on the floor, or anything a mess for me to clear up, he just seems to be incapable of opening a cupboard and putting anything in i and/or shutting it properly afterwards
He gets DIY materials out to do a job, and when he has finished. leaves his tools on the kitchen table in a neat and tidy pile. I am sure it is something programmed in.
