It’s logical, isn’t it?

People who choose to stay married should be happier in their relationships.

After all, it’s easier than ever to exit a miserable union, people tend to wait longer before making the jump and many just don’t get married at all.

Despite that, the number of Americans who say they’re “very happy” in their marriages has fallen from 68 percent in the early 1970s to 60 percent.

There are four types of people who tend to be happiest with the quality of their marriage: those who spend more time at religious centers, people with extreme political views (skewing to either spectrum), those who describe themselves as upper class—and men.
