This is fuck all to do with his disability and everything to do with him being a lazy entitled cock-lodger!
I have heart failure - which means I struggle to lift my arms, some days typing is hard and I am a good and fast touch typer, just to give you an indication of how badly affected I can be...
I use a power chair due to Ehlers Danlos and the heart failure and spinal stenosis and my house is not very accessible at all...
And yet - if the laundry is all downstairs in the basket, I'll load up the washer, move it from washer to dryer (they're opposite each other so I can do this), take it out the dryer and fold on the worktop.
If the worktop is clear of stuff, I can wipe it down, do the cupboard fronts and fronts of the appliances (not quite to floor level though I got a short little moppy thing for that but its not the best job!).
Sweep and mop the floors, hoover if someone plugs it in (need to move our powerpoints really but tahts a Big Job on the list of Big Jobs)...
I tend to mop and hoover in the living room, hall and kitchen - I cannot wash up, I can't get close enough to the sink and I can't currently cook for the same reasons - can't get close enough, worktop is too high - but soon (fingers x!) the kitchen will be accessible and we'll have a slimline dishwasher so I'll be back to cooking and sorting out the pots too.
I also work part time from home!
DP does the bits he can do, and he does care for me for the things I can't do, and works that around his own disabilities, and I manage the bits hes not good at.
It's not always perfect and our house won't win any tidy homes prizes, but stuff gets done!
Yours... can't be arsed, probably because he knows you'll do it, and you'll take the bullshit from him as well.
Stop doing it, stop taking his bullshit!
