Tom's ruse didn't last long. Money is what couples fight about most. They battle over how to manage it, who should manage it, how to spend it. It's about how money is spent and managed. Not all couples have money conflicts, but most do at some point.
Many partners laugh about and learn to live with their differences.
The key is not whether a couple argue about money but how they work things out. Disagreeing about money is normal. The battles can be subtle. One person may lecture the other about switching off lights. Or a husband doesn't bother to tell his wife exactly how much he spends on lunch.
