When you were courting, did you talk for hours about current events or the meaning of life? And now all you seem to talk about now is the grocery list or how much to spend on a new sofa? Asking about each other's day isn't enough.
Try this: One night while you're in front of the TV or in the car, make a remark about something your partner deeply cares about that's bigger than the both of you—sports, politics, anything to get the ball rolling. Keep it rolling! Also, don't forget to share funny stories too; a recent study found that sharing humorous experiences significantly reduced the amount of conflict couples felt.
