I highly recommend this book for anyone engaged or married (one man & one woman). If you love your spouse, you will learn to speak their love language and the rewards will be outstanding. So much God given wisdom in this book. It is like an awakening and can make a marriage better with just a little effort and understanding how your spouse receives love
