Could it be the other partner comes from a family with maid/helper?

It boils down to their up bringing. If the his/her family has maid/helper, then their tendency is to let other do the work.

My brother-in-law, since childhood, mother bring his plain water whenever he asked for it. When he married, his wife do the same. Until today have not seen him lifting his hands to get water or wash the cups.

Perhaps TS'husband is like the above.
