The first years of marriage

More than the paperwork suggests, though mostly quietly. Responsibilities and expectations towards each other grow, and the first year is described as an important and sometimes difficult time of adjusting to a shared life¹. Nothing about your Tuesday changes because of a certificate, yet "we" can suddenly feel weightier.

During this adjustment period, couples size up how each of you handles empathy, problem solving and getting through difficulties, and start to see what kind of life you'll have together¹. That's less romantic than it sounds, and more useful.

The honeymoon glow also tends to settle. Newlyweds often hit an adjustment bump in the first year, once the haze of romance fades and real life (the schedules, the laundry, the third "what's for dinner?") sets in².

On average, satisfaction starts high and drifts down over the newlywed years³. But averages hide a lot. Some couples show no decline, some a small one, and a few a large drop from a low starting point³. In several sets of data, most spouses showed little or no change: between 60% and 85% of newlyweds had minimal declines over 2.5 to 4 years⁴. Where couples end up seems to depend a good deal on where they start⁵.

So it helps to expect a period of adjustment and to talk openly about what each of you expects from shared life. A dip in the glow is common. It doesn't mean something is wrong.

For most couples, less than you might expect. Satisfaction tends to stay fairly stable for long periods⁴, and the differences between couples appear largely early in marriage⁵. How a couple starts says a lot about where they end up, which means many of the things that shape a marriage may already be in place by the wedding⁴.

Some change is still common. Satisfaction starts high and declines for the average newlywed, and marriage adds responsibilities and expectations^3,1.

Snapshots comparing married and unmarried people do show differences. Across eight European countries, people who were cohabiting more often had breakup plans and were less satisfied than people who were married⁶. Married people also reported greater life satisfaction and less psychological distress than dating people who lived apart⁷. These are comparisons at one moment in time, though, and they can't show that marriage caused the difference.

Early unhappiness is worth taking seriously. After 4 years of marriage, 3%–14% of spouses in the three most satisfied groups had ended their marriage, against 25%–54% in the two least satisfied groups³. That's an average, not a forecast for you two: many spouses who were unhappy early stayed married, and some who did well early still divorced³.

So rather than assuming the wedding will change things on its own, talk about how you want shared life to work.
