If you don't ever have to worry about your wife losing her job, and the job you have now is not enjoyable, and doesn't pay well, I'd see if by staying home, you could save as much money as that job is paying you. So see if by staying home, you can do all the chores in the most efficient way, never use your car because you've got the time to ride your bike everywhere, cook every meal at home, etc. See if all that would add up to saving what you currently get paid, and then your choice becomes pretty easy. If not, well then the choice is still gonna be hard, but I'd hate to push FI back further... just personally.
