Jennifer Weiner uses her long history of various relationship types to share insights on how to keep the romance alive, what makes two people really compatable, how to disagree without actually fighting, how to communicate well with your partner, how to cope when your partner has an illness, how to communicate openly about sex and intimacy, and more.
Jennifer takes a no holds barred, no BS, no fluff approach when she gives advice--both in real life, online and in her writing. She also may drop and F bomb or two, so if mature language bothers you, you will probably want to find a different author to get your information from.
Jennifer also does not include religious context into her advice. If you have read her profile, you'll see she's of a less than main stream faith. However, she accepts all faiths and believes you should work her advice into what your faith say about relationships and marriage.
