Oh my, now this is something I can relate to.
Maybe not the degree but certainly the feeling of "walking on eggs".

The more control they loose to the disease the more they try to control other things, at least in my experience.

Hubby did try to keep these feelings to himself but I could tell how nerve wracking it was for him not to have everything neat and tidy. That made me twice as tense and responsible for making the home life "perfect". I tried so hard.
Then seems like when he was the most miserable a routine set in.
After each treatment
dinner
long hot bath
bed

He didn't have much energy to even notice things on the floor unless they tripped him. He had no desire to even look in the silverware drawer much less inspect it. Things that bothered him to no end before weren't important.

Now everyone is different in how they handle things.
Hopefully he will back off and give you some space.

If not....... vent away here.
