Do you have a high CN? My suggestion would be for you to get married before your CN becomes current, then send out new sets of forms to KCC (I'm assuming you already sent out your own form to KCC), for yourself and your new wife (again assuming you the selectee are a guy). You will need to include a copy of your marriage certificate with the documents you're sending to KCC.
When you go for the interview with your wife, you will need to prove you guys had been dating for a while before your marriage, you will need to provide pictures taken when you guys where dating, marriage pictures, evidence of on going communications before the marriage, etc. The CO may ask questions about how you met, when and where you met each other, things you guys did together, places you visited together, etc.
