The bigger the wedding guest list, the better the marriage, according to a new study.

So if you want to live happily ever, after make sure lots of people are at your wedding.

That’s according to a report from researchers at the University of Denver and the University of Virginia in Charlottesville.

According to the data, less than a third of the couples who had less than 50 guests at their weddings reported a “higher marital quality.”

The percentage of quality rose according to the number of people at their big event.

Not everyone says “I do” to the findings, however.

Psychologist John Gottman from the University of Washington, who has studied marital stability for nearly half a century, refutes the claim, saying trust trumps all.

Nearly 1,300 people were involved in the survey.
