You may believe that you know the person with whom you are walking down the aisle, but do you know the person that he/she will become after the vows are spoken? What changes take place with the placement of rings? What are the critical issues that you might be facing that you had never addressed, or thought you had addressed?
For example: how will you handle money, friendships and family, children, hidden addictions, sex, and cheating? While not insurmountable, they can become overwhelming, and potential battlegrounds for the war that has so often become marriage.
Learning to navigate the battles, and choosing the right weaponry, can help you to win the war without destroying the relationship-or yourself.
