So close, but so far away

There are about 7 million couples in the United States who are together despite living in different cities (and 50 percent of college freshmen are in long-distance relationships). Undoubtedly their relationships are quite different from those benefiting from geographical proximity. Here are a few things that set them apart:

• On average, they see each other 1.5 times a month.

• They call each other once every 2.7 days, and their calls last about half an hour each.

• The average long-distance couple plans to live apart for 14 months.

• The distance between them is about 125 miles.

• Couples in long-distance relationships report the same levels of intimacy, satisfaction, trust and commitment as those who live in the same city.

• They write each other three letters a month.
