By the time couples reach their 40s, life tends to look stable on the surface—steady jobs, maybe a mortgage, and hopefully some retirement savings. But behind that sense of security, many are realizing that certain financial decisions made in their 20s and 30s have long-term consequences. It’s often only in midlife that the real cost of missed opportunities, unchecked spending, or poor planning becomes clear. Fortunately, learning from these common missteps can help couples regain control and make smarter choices going forward. These financial lessons may come late, but applying them now can still make a big difference.
