I've never been a believer in "love" as the sole prerequisite for marriage, so this book seemed interesting to me because I felt it was perfectly in line with my way of thinking. Unfortunately, although good, the book falls short on another of my long held beliefs---marriage just doesn't work in the long term.
This book serves to cement my belief that marriage, as a whole, is an outdated social construct that rarely outweighs the test of time in our current culture. Prior to the days of women becoming educated and having the ability to fend for themselves, marriage had a place. Most women were completely motivated by financial constraints to make their marriage "work". Men, having no domestic skills, were also motivated to remain in terrible marriages.
Now that women and men are equals in life, the workplace and social situations and there are no longer stigmas on women and men who have sex outside the confines of marriage, what motivators are there to keep a marriage together (let's not even mention HAPPY) for decades?
Obviously, the dynamic of raising children changes this slightly, but not completely. Children require parental supervision and care for only a mere 18 years---after this time, they are left to fend for themselves. Most marriages can last happily for this amount of time, especially since the distraction of caring for offspring takes focus away from the interpersonal relationship of the couple.
I believe love exists. I believe good relationships can be built, I'm just not sold on the notion that "marriage" and "partnering" are valid. I believe we are trying very hard to maintain marriage as a moral norm of society that no longer makes much sense.
