Beauty is in the eyes of beholder, and eyes cannot deceive the beholder. If a woman is beautiful, we would see her as beautiful woman. If a woman is not beautiful, we would see her as not a beautiful woman.
But love is in the heart of the lover. If we love our wife, we would always feel that she is the most beautiful woman in the world although our eyes say that she is not beautiful.
Always grateful with the woman that Allah has given to you as your wife. So you will always love her and will always see her as the most beautiful woman you have ever seen in the world, whatever her condition.
There's no happiness as Muslim husband more than happiness when your wife kiss your hand after you lead her in salah.
