Our couple's exercise for this week is called the great exchange. Very frequently, couples take each other for granted. As time passes, appreciation elapses into nothingness.
This week, practice showing genuine appreciate for one another. Take time to notice the things done for you by your spouse. Really pay attention. Then, listen for cues as to what you can do to make his/her day easier, or life less hectic. Do them, even if you don't want to. Within a week, you'll see a major improvement in your marriage.
