Dollar-cost average your marriage

To all my married friends & readers, and those interested in one day being married, I read this interesting article in the NY Times about finances and marriage. It contends that the number one source of strife in all marriages - as well as a major reason for divorce - is financial. It encourages people to date their "financial twin" to avoid some troubles, and for everyone else, it cautions that the pitfalls are many & that the need for communication -- specific to finances -- is essential. In fact, to put it in terms many of the NY Times' financially-savvy readers would understand, the article encouraged couples to "Dollar-cost average" their marriage. I.e., instead of waiting for the "right time" to make investments, always invest (communicate, go on dates, update budget, etc.) at frequent, regular intervals. Then after many years, the dividends would roll in.

While I'm not sure I agree with everything in the article (it's written from a purely secular standpoint, and essentially leaves out the role of wise counsel & prayer), it seems a definite starting point. What do you guys think?
