Describing the way social media began to interfere with his own marriage, Kerner, who has since come off Facebook entirely, says: “I realised for a little while with my own wife that I didn’t really want her to be my friend on Facebook.”

“I didn’t want all of that extra information. If anything I wanted less information — I wanted more mystery and more unpredictability.”

“I didn’t want to know that she was posting about being tired or having her third coffee for the day. So I specifically unfriended her during my brief tenure on Facebook.”

“It’s something that I do recommend to couples.”

Along with unfriending each other, Kerner also advises that couples make a concerted effort to switch off their devices when spending quality time together.

“When you add up all of the periods of distraction that devices give us, you might have a lot of time that you could put towards your relationship.”

“We live in a culture where sex ruts are epidemic and people go to bed too tired to make love — they have no time for each other. And yet they’re spending hours a day on social media, on blogs and on Netflix.

“Maybe we really need to figure out how to turn off that faucet.”
