There aren't many items you can buy or organizations you can join that will not come with some sort of manual or handbook. However, when you get married, you don't get anything. It's all trial and error. The manual will instruct you on how to properly utilize your new purchase and the handbook will define the purpose of your new organization along with its proper etiquette and protocol. Again, you get married and you get nothing. About 50% of all marriages end in divorce. It has to be admitted that many entering are simply unprepared. Many approach marriage with the same understanding of dating teenagers. When an ill-equipped person faces a challenge in their marriage, they resort back to their teenage knowledge in finding a solution; they breakup and find someone new. In a marriage however, there is no breakup and find someone new; this time it's divorce and remarry. Getting married is one of the greatest decisions you will ever make; shouldn't you at least try to understand it?
