There’s a difference between disclosing details about your own personal finances and talking about the kind of financial issues (in a generic rather than specific sense) you feel are important to discuss as a couple before marrying. I think of your story as modeling that kind of good, open communication and partnership in financial decisions that you and your wife have, rather than an inappropriate divulging of too much of your personal financial data. That’s great, and you should both be proud to share your story!
