Love The One You're With by Emily Giffin is the story of a married woman who runs into her most serious ex-boyfriend on the street and revisits her feelings for him. He sends a wonderful professional opportunity her way, and it leads to the two of them spending time together and keeping in touch over the phone and e-mail.
Set primarily in New York City and Atlanta, this is a story filled with incidents, which, if looked at independently, would lead you to think that the heroine was selfish and disloyal. But the character development in the book is so well done that you connect to her, you relate to her, you know why she's doing what she's doing. Not like Love Aaj Kal, where the character development is so pathetic that the heroine looking for her first love after she marries someone else comes across as selfish and a little ridiculous.
When I shut the book closed at the end, I felt good about it all. There's a certain feel-good factor to it all. It's a story that tells you that everyone is human, everyone makes mistakes, but if you want to, if you really want to, it's never too late to make amends.
I really like the last sentence of the novel where she says that love is about the sum of our choices, the strength of our commitments, the ties that bind us together.
