Overall, I have to agree with the assessment of the article. My personal case worked out a bit differently, but only because of a direct promise to God. My wife and I lived together for seven years, then broke up for seven years. Circumstances happened, and we got back together. Part of the circumstances that led us back together was my return to the Catholic Church after a twenty-year hiatus, and her conversion to the Catholic Church. If not for the Catholic community treasure, we would most likely have not gotten married. But when we reconnected, I made a solemn promise to God that I would marry her and make it work. She has been the only woman in my life for nearly 35 years (even when we split, I did not chase around, but spent my time getting square with God). While I would not recommend others trying our path; it worked in our case, but it has been a wild ride up to about five years ago. Pax domini sit semper vobiscum.
I have to agree - for me I made a commitment not only in front of God but to Him. I am far more concerned with the keeping of that relationship as well as the one with my wife than just a wife alone! A true belief in the reality of God tends to, mostly, keep me on track in most area of my life! Not that I am any paragon of virtue bit I can imagine how bad I would be without that belief!
