AMEN!
Gonzo, you said earlier that you did not know why people who live together before marriage are more likely to divorce. I believe the answer lies in the declining morality of our world. If you yourself and your future spouse think it is OK to live together and participate in sexual behaviour which is only sanctified by marriage (according to the Bible), then the odds are that you and/or your spouse probably possess a number of other un-biblical, self gratifying beliefs which could easily lead to divorce down the road. I.E. Adultery, selfishness, lying, self reliance, etc.
I am glad to hear that you and your wife have apparently (thus far) managed to remain committed to one another, but I would suggest that you are the exception rather than the rule. My own former marriage is a textbook case of two people who came together under sinfull circumstances for sinful reasons, lived together, got married, had a child and then divorced.
Now I was baptized when I was @ 12 yrs old and my father is a minister, but I turned my back on all that I knew to be good and true because I believed I was in control of my life. It took the breakup of my marriage... my family to make me realize just how vain and pathetic I really was. In the darkest hour of my life, when I had lost all that I loved, I felt God's presence for the very first time. He had been there all along waiting, patiently, for me to stop focusing on myself, turn my attention back to Him, and ask Him to fill my heart... my life... which was, then, so empty that I wished for death. I accepted the gift of His grace which is so simple that it seems too good to be true, that He (Jesus) was the Son of God who came to this earth to die as a substitute sacrifice for the sins of the world and that all I had to do was believe in Him and ask him to come into my heart and take control of my life. It was nothing short of miraculous, the transformation that then began in me. In the worst time of my life I actually felt joy beyond any that I had ever felt before and peace despite the "storms of life" which were raging around me.
God did not arrange my divorce so that I would return to faith as the prodigal son, but he did take advantage of that "teachable" moment in my life to show me the path to salvation and contentment in this world. If I ever consider marriage again, it will have to be with a woman who loves God more than me. If my X-wife had been that sort of woman, I know that we would still be married today and happily too boot.
My point is that had my wife and I been living for Jesus instead of ourselves, our marriage would have never ended. Even if you don't believe in Jesus or God please recognize that the moral standard you live by has a direct impact on your marriage. Therefore, we should strive to live up to the highest moral standards (which would include not living together or even having sex before marriage among other issues) if we wish to have any hope of lifelong committment.
