Calculating your value vs the mother or father of your chlidren Is sad isn’t it?
Why would anyone do that unless they were thinking that the marriage might break-up?

It makes sense to have repect your family’s values about having a stay at home parent and only your family’s values. Inevitably there will be thinking about the economic tradeoffs, but that’s different than sweating it once you have an agreement. If you don’t like how it evolves, or fear where it could lead ,then it is imperative to find a solution and I guarantee it is not the math problem of how much a sahp’s work is worth.

And for godsake , CARenter, please quit calling it “women’s work” . How sexist can you be?
