For the person interested in reading and learning more about all aspects of affairs (which I highly recommend), I have written personal reviews of some of the best books on the subject. Frankly, I have found that those people who do the most reading/thinking/talking about the whole issue usually do much better in dealing with it.
Note that on each of the pages reviewing a particular book, I have also provided a link directly to the page on Amazon.com where that book can be ordered.

Books about Affairs
This page provides links to my reviews of 16 books.

I have also reviewed books on other subjects:

Books about Marriage/Divorce
This page provides links to my reviews of 15 books about marriage and divorce.
(Five of these books about about divorce.)

While there are fewer reviews on other topics, I have also posted a few reviews on:
Parenting
Life
Personal/Social Issues
