Now, according to therapists, there’s another intimacy-killer in our midst: the iPhone.

NPR’s Jennifer Ludden reports a spike in the number of couples complaining about each others’ overuse of technology, and questioning whether the digital age is chipping away at our marriages.

Tara Fritsch, a marriage counselor in Edmond, Okla. “is hearing more and more clients complain about a spouse whose body may be right there but whose mind is off in cyberspace. Some say the best way to get their spouse’s attention is to send a text — from the next room!

Others complain that a spouse’s late-night e-mailing cuts into their sex life.

“Closeness depends upon this rapidly disappearing phenomenon of undivided attention spread over time,” says Edward Hallowell, a (Arlington-based) psychiatrist and co-author of Married to Distraction. Just think how hard it is to complete a work project amid a stream of interruptions, he says. “What you give up at work is depth. And what you give up in relationships is intimacy,” Hallowell says.
