Type Talk by Otto Kroeger and Janet Thuesen
Type Talk - The 16 Personality Types That Determine How we Live Love and Work, is a great book to help you understand and accept your partner and your differences, and hopefully learn to laugh and celebrate them! Based on the work of Jung you can easily determine your Myers-Briggs Type on internet sites.
Armed with this knowledge learn more about your self and your other half in the book. There are 8 different preferences. For instance you could have a strong or high score for the "J" or "Judging", tendancy. These types are often highly organized and like to know what's going on well in advance. If you are married to a P, for "Perceiver" they like to go with the flow, last minute changes are fine... this can create a challenge. Many men are "Thinkers" and many women "Feelers."
While of course we can not put everyone into little cubbyholes, distinguishing which of the 16 different types you and your partner are will bring much insight into your relationship.
