This made me recall and realize that a certain period, about two years ago, when i had gone to visir a relative, the both couple were mostly on their phones. Wife runs an online business, husband mostly travels for work. Wheneber they're togetber, it's like they're flatmates. They talk, though, but not very well as one would think. It's just somehow.
The pattern that you and your spouse have taken up would be of great benefit to your bond, moreso in the long run.
