Part of being a responsible mother/housewife is having backup plans in case your spouse becomes unable to work (has an accident, loses his job, or many other common life events that can happen to anyone at any time).
Anyway, what's done is done. The VisaJourney forums are full of info from people at every stage of the process. You have the opportunity to research, plan ahead and learn from others' experiences. Good luck with the rest of your journey.
