Our cultural vocabulary indicates that marriages move one way--downhill.
The "honeymoon period" implies post-honeymoon strife; the "seven-year itch" suggests that we tire of our mate at year seven.
Now, Wright State University psychology professor Lawrence Kurdek, Ph.D., confirms that our lexicon is accurate. His surveys of over 500 couples have revealed that most married couples experience a gradual but steady decline in marital quality over the four-year period after they tie the knot. Newlyweds tend to wear rose-colored glasses at first, says Kurdek, but reality kicks in after they see their partner drink from the milk carton or forget to take out the trash one too many times. Though happiness stabilizes after four years, it declines again around year seven. This dip is harder to explain, Kurdek says, but may stem from the tendency to reexamine life as time goes on.
