I can think of quite a few RL examples where men have been in this situation with their wives who have a particular expensive and time consuming hobby, and had very one-sided relationships, but really the responsibility is rather on toxic masculinity as an influence in why those men chose these very materialistic and selfish women rather than someone who would be an equal partner to them.
Seeing these men trotting round after these particular selfish women (way over-represented in this hobby), helping like a servant and paying for everything was nauseating and yet in this particular hobby not uncommon, and frustratingly, at the time I was single and looking for a relationship, there seemed to be plenty of men who would self-harmingly choose and facilitate these women, (some who took it as a price to be paid for other attributes and/or who put the wives on a pedestal, the 'my lady' fantasy, and did not actually see women as people and value human qualities such as kindness and fairness but were attracted by narcissistic high spenders, perhaps mistaking narcissism for demanding respect, a la other men, 'successful' men in the hierarchy), and at the other extreme many men who expected to be put first, would not accept that a woman had her own time consuming interests and behaved quite stereotypically selfishly, and very few men in between. Needless to say I was attracted to neither type.
I see this is the product of toxic masculinity and patriarchy and capitalism as much as anything. Nothing to do with fairness or feminism or women who want a man to be a caring responsible husband/father.
I think perhaps "wait on him" is American for "wait for him".
