The most effective way to do this is to reunite at the end of the day and talk about how it went. We call this the “How was your day, dear?” conversation, or more formally, the Stress-Reducing Conversation.
The one rule is that you can't talk about your marriage. This is not the time to discuss issues between you. Instead, it's an opportunity to support each other emotionally concerning other areas in your lives.
If you have this sort of conversation every day, it can't help but benefit your marriage.
