What do ordinary couples rely on for communication? You'd better call God for help when you meet.

That depends. There are many couples who can meet often. There are also many face-to-face conversations. But telephone messages are also essential. Phone calls and text messages that you don't meet often are more intensive. Meeting has the advantage of meeting. You can observe each other's various situations when you meet. Like mood or something. But there is a lot to say when we meet. You can say it on the phone and in text messages.
