A big risk in long-term relationships is taking one another for granted. No matter how much you love and appreciate your spouse, there's always a risk that you might get so accustomed to one another that you forget to be grateful for all that your partner does. If you make an effort to express gratitude, your partner will almost certainly do the same.  Say thank you when your spouse does something for you, whether it's cooking a meal, fixing a broken cabinet, or just picking something up for you at the store. Letting your partner know that you appreciate the little things will make your spouse feel appreciated, and your partner will be more likely to continue doing nice things for you (and vice versa) in the future. You could say something like: "It made me really happy that you swung by work today - thanks for doing that. It was good to see you for a few minutes." Another facet of taking your partner for granted is forgetting to compliment one another. You may think that your partner knows you love him or her, and that may be true. But nothing brings a smile to your face like hearing that someone finds you attractive and desirable, so work to make one another feel special as often as possible.  It doesn't take much to notice your partner. Compliment your spouse on an attractive outfit, a recent haircut, any developments after beginning a new workout routine, and so on. Try to praise your partner for his/her efforts in front of others. Bragging about your spouse's accomplishments when he or she is too shy to can really make your spouse feel loved. As your relationship goes on, you might find that it's harder to make time for a date, or to go out and have a romantic evening alone. This can be particularly troublesome if you have children. But having regular date nights spent alone with your spouse can bring back the excitement and the passion that you felt for one another when you were actually dating, and that passion is important in sustaining a long-term marriage.  Commit to spending the night alone...
