You have to think of the pros and cons of your choices. For one thing, a lot of people get married through civil rights then gets a church wedding after saving up. Consider it as a gift to your wife and to yourself. The primary reason that we are working here is to save up money so we can fulfill our dreams (i.e. travel, wedding, house etc.) Getting married in church is a dream come true to women. Anyways, talk things over with your wife. Your fellow QLers can only give suggestions but it in the end it will still be up to both of you.
Best Wishes!
