The New York Times has an opinion piece in support of traditional marriage, and against cohabitation:
I’ve had other clients who also wish they hadn’t sunk years of their 20s into relationships that would have lasted only months had they not been living together. Others want to feel committed to their partners, yet they are confused about whether they have consciously chosen their mates. Founding relationships on convenience or ambiguity can interfere with the process of claiming the people we love. A life built on top of “maybe you’ll do” simply may not feel as dedicated as a life built on top of the “we do” of commitment or marriage.
The article concludes with the usual liberal ego-stroking we've come to expect from contrarian contributors to the Times, but overall it makes a strong argument for traditional marriage. Has hell frozen over? In the past year alone, I think I've read three or four anti-marriage articles in the Times. However, I do not read the paper on a regular basis, and it's possible there are other articles in support of marriage I missed.
