Are you suggesting the mother derived no benefit from the arrangement, that she continue to pay half the rent, health insurance, groceries, car insurance, gas, etc?
Personally, when my wife didn't work for over a year (more like two), it did fuck all for me. I paid all of the fulltime childcare, took care of the kid before and after school, and paid every single financial interest of my wife except her car insurance and phone bill. I can truthfully and honestly say in my personal situation I got nothing out of it. I paid for her because I love her and wanted her to have the same standard of life I have WHILE WE ARE MARRIED -- but I would be quite displeased indeed if my generosity in marriage is taken to mean I would be so generous after being ditched.
