This was a good book that talked about as its title says marriage, family, and all sorts of interpersonal relationships, but mostly romantic relationships. This book was filled with mostly statistics and how to improve communication and overall satisfaction in your relationships to make them better.
My biggest complaint is that it focuses on American, Euro-centric and white marriages and families. I find it sad and very frustrating that despite the U.S. being a very diverse, multicultural, and ethnic diverse nation, there is very little research and such little known information on racial/ethnic minorities living within the U.S.
Still, despite this, it is a solid read in understanding American white families. And it still can somewhat be applied to families in general, but you should view it with the thought that this may be irrelevant to different cultures outside the U.S. despite cultural minorities also living in the U.S. as again this country is diverse.
Hopefully more research will be done on minorities in and outside the U.S. as we matter too.
