Keep up appearances. While physical attraction is only one part of love, in our visual culture, it plays an important role in how we think about and relate to our partner. When you go out with your spouse, dress nicely to show that you consider your time together special. Take care of your health, too. Eat a nutritious, balanced diet with lots of fruit and vegetables. Aim for thirty minutes of exercise each day. Dressing well and taking care of your appearance will keep your partner attracted to you.
