WCW, Sorry about your lawn sitch. In our R my H is the operator/driver and I am the "laborer". Lol! I assist. But he gets to do the fun stuff like drive... I keep the records and numbers for oil, filter and belts etc and hand him tools when he is wrenching. I get to rake it if he has waited too long between mowings, and I always get to pick up sticks and the dog poop so that he won't run them over.
If H vacated and left and didn't help me with things, I'd find someone to "help" me 'git-r-dun'.
I learned early by watching a gf who does everything around their house. He never mows or showels snow or paints or anything. The more that she does, the more he lets her do. I guess once you've started it's hard to go back.
With my H., there are some things that he needs to feel in charge of.
Most of us are about as happy as we make up our minds to be.
