Episode 3: Tracy discusses money lies between partners and what crosses the line between ordinary money behavior in a couple and financial infidelity, noting that secret spending, lying about purchases or mild violations of the family's money rules move quickly to a dark place. She ntoes that most adults 'know it when they see it,' though that doesn't stop them from doing it. Further, she notes that it's often the secret-keeping and the dishonesty that matters more than the actual dollars involved. To avoid the fate of Derrick and Jackie -- featured in her book and whose financial infidelities were hiding other problems that led to divorce -- Tracy remphasizes that looking at the paper trail in search of financial infidelity often uncovers other financial challenges that couples benefit from facing together.
