My wife and I are raising 4 children on a graduate student’s income - and she is staying home with the children. Good women are out there - you just have to look in the right places like someone else posted. You just have to find one who cares more about her values than about “keeping up with everyone else”.
When you say a grad student’s income, you mean the income you get from having a master’s or higher degree, right? You don’t mean your wife stays home and you go to school on an assistantship, do you?
