Power Browing: A source reliable?

In this article, Eric Sentell talks about how cohabitation before marriage has become a normal thing to do compared to 60 years ago when it was abnormal. However, he still does not believe it is the right thing to do. In a 2002 survey, it says that 28% of women in their thirties had cohabitated before marriage. The survey came out to show that those who cohabitate with one another are just as likely to get divorced as those who don’t.

In this article, the author talks about how usually cohabiting couples live together before marriage because it decreases the burdens of single life. They view their partner more as a roommate than as a serious relationship. The article says that those who cohabitate before marriage are 50-80% more likely to get divorced.

This source gives reason to why people are moving in with each other before marriage. One reason is that they want to decrease living costs. Another reason is that people find the institution of marriage has become less concrete, and they do not want to commit.
(Author- No, mission is described on document- yes credible source--> the facts that it gives can be credible, however they are not very strong.)
