Houses can be sold, especially in this market, a seller's market. Cars can be sold. Children don't need to be spoiled.
(And don't say you married for kids if you spend all your time at work instead of with them.)
This is neither sickness nor poverty. It's simply not being fabuously wealthy.
Another comment talked about living in a "cottage". Why do we need to exaggerate? Not having a high-earning job simply makes you normal, like most other people, indeed most other married people.
