I’m confused, why would you be jealous here? Aren’t you and your wife “life partners” so to speak? That means understanding what money means to each person, understanding your partner’s money goals, and working towards shared financial goal.

Honestly, it sounds like you two need to have a heart to heart on this and figure it out, because frankly, you’re behind the curve on this. And if it’s not going well you should seek counseling. It’s important for a couple to be on the same page regarding money.
