When one spouse wants to save every extra dollar while the other thinks money exists partly to be enjoyed, the household budget can start feeling like a tug-of-war. One person sees a growing savings balance and feels calm, while the other sees that same balance and wonders why the money is sitting there instead of funding a trip, a nicer dinner, or something fun.
Neither instinct automatically makes someone right or wrong. Saving provides a financial cushion and helps fund future goals, while spending can add enjoyment to the present and keep life from becoming one giant exercise in postponement. The real trouble starts when spouses stop treating the difference as a financial preference and start treating it as a character flaw.
