Malachite your question sounds alot like something my husband often said he likes things orderly and organized and often said "there is a place for everything and everything has a place ."
May I ask how extreme are the two of you?He was I believe OCD where the remote control for instance had to be on the tv every night my kids left it on the couch a few times to much so he was so mad he smashed it against a wall,same with a jar of peanut butter left on the counter one to many times instead of put in the cabinet .
He lived alone 13 years before meeting me,(he only had himself to keep up after and 1 persons stuff) a mother of 4 sons 7 year span btween the 4 of them and saw my house ,dishes were clean,toilets clean,floors vaccumed and washed but I also had clutter newspapers on couches,mail on the table a couple boxes here and there in every room etc.things that needed cleaning for sanitary reasons were .
On the other hand his house looked like a model home as if no one lived there perfectly placed pictures on walls,no mail in site,no newspapers,towels folded in an exact manner(he took over laundrey after we married,which was ok by me,I didn't fold towels or shirts the way he liked anyway)he would complain I wasn't organized enough for him .My response I have had over 20 years of living like this raising 4 boys my prioroties weren't making sure I was working FT after working FT it was to enjoy them.I also told him if he helped me I would better be able to maintain things.Well never got to that he was always working on his house in his spare hours repainting new colors etc.which I helped and left me 5 years out we have been seperated an additional 5 years he has a gf now for 2 years that lives with him that i'm sure keeps the house orderly and clean to his specs.
My point I guess is if she has always been this way she may always be.If she is willing to change ,help get things the way you'd like,if you are extreme the way my ex may have been it may cause you both alot of stress (her worried its not good enough for you,you stressing over chaos).

Or Do the things yourself to your standards but don't make her feel like she isn't good enough to do it .Some of us have certain things that cause us stress and satisifaction.

If she were somewhat Oscar and you somewhat Felix when you met keep that in mind and neither of you should complain or hold it against each other now.I know personally I got better and when he left I strayed again and his OCD got worse when he was back on his own again ..
