Maybe you can approach your spouse like this? “Honey, I want to build on “Our Time, when we can shut off the world”. I will shut off my external world (cell phone) when we are eating. Honey, I look at eating as a time of intimacy, catching up on today’s events, a time of silence, and a time that it is only you and I against the world, so romantic. Just you and”! Trust me; it is not a culture difference. Sometimes one must express the real reason for wanting time alone with each other! LOL
