Why Did This Turn Into An Argument?

So My Finance (Female 24)
Got Mad Because I Asked Her To Clean The Baseboards It's The Only Thing I Ever Ask Her To Clean Like 1-2x A Year.

She Claims It's Her
(Do Nothing Day)
She Works Full Time And Goes To Nursing School 3-4Days A Week.

(She Claims She Will Never Have Any Other Days Free)

But We Have 2Cats And A Dog That Makes Messes Non Stop It's Like Having A Toddler Full Time By Myself At Home) The Carpet And Floors Are A Mess NonStop Because Of Hair... The Dust Is Always Bad. Laundry Room Also A Mess Because Of Cat Litter..

My Osteoarthritis In My Joints Are Painful So That's Why I Gotta Skip Doing BaseBoards
(She Does Know That)
(5+ Years Now)

She Goes Into Panic Mode Over It When I Ask Her To Clean The Baseboards. The Baseboards Get Covered In Dust And Cat/Dog Hair.

I Work But Because Of My Health I Can't Work Enough To Really Pay For Anything OutSide Of My Phone Bill And My Medication I Lose 60% Of My Money To Taxes And Child Support.

I Clean Pick Up After Her NonStop I'm Fine With That I Do Laundry Make Her Food For Her Near Daily.
Feed The Cats Daily Clean Their Bowls Daily Same As The Dog. Take The Dog Out 2-3x A Day. Do The Floors 2-3x A Week Because They Get That Bad. Do Laundry 2x A Week. Do Dishes 1-3x A Week. Clean The Cat Box Weekly. Sweep The Floors 2x A Week Vacuum Floors.
I Do A Lot Of Stuff.

I Know This Is All Over The Place. I Know This Is Normal Stuff. But Why She Gets Mad About Me Asking Her To Do Literally 1 Thing 1-2x A Year?
