I have every sympathy but he's still only a child, albeit a child on the cusp of puberty.
I did absolutely everything for mine because I, unlike many working mums, was able to stay at home.
Still, they did have job, paper deliveries for the boys and magazine drops for the girls but to be honest, I used to do it for them when it rained.
When they started work and luved awsy from home at 16, they learned (by trial and error?) how to launder, cook, clean
and budget their money.
When they married their wives never got a look in. The (now) men do it so much better.
There was never any need to teach or cajole them but not all males are the same...thank goodness. 
I think MissAdventure is doing a sterling job under difficult circumstances but the boy will be a man soon enough. Enjoy your children/grandchildren while you can.
