I think he meant spend time interacting with each other, not just being in the same room together and being in their own worlds.
I know exactly that he means. Many people I see are in the same room, but absorbed in texting/TV/laptop and not interacting at all with each other. I've seen couples in restaurants where one is reading the newspaper and the other is on the phone. That's not really going out together, when you think about it!
Time with each other in each other's company is important!
