Do something special and out of the ordinary for your spouse. Something you would not normally do or they would expect like wash her car or clean the kitchen. Maybe you make his favorite dessert or watch that sporting event with him. Do something that will say that they are special to you not for what they do for you but for being themselves.
Continue to control the negatives and give positives. Keep up the meeting and leaving attentions. You are one-fourth of the way along this path. Make a note of what you have discovered so far.
