Love The One You're With by Emily Giffin is the story of Ellen, a woman who is a happily married newlywed, or so she thought, until she runs into her ex-boyfriend and can't get him out of her head. Ellen has to decide whether to choose to stay with her husband, a perfectly nice guy who is oblivious to her dilemma, and the one that got away, who is kind of a jerk. The story is meant be light hearted and funny, but, although I wanted Ellen to be happy, her problem had me frustrated with her and uncomfortable with her possibly choosing her ex over her sweet husband. I did enjoy the book and I am a big fan of Giffin's writing, I just was a little disappointed because I had been looking forward to reading the book for a while and felt slightly let down. It was a good book and I did enjoy it, I just didn't feel it was quite as good as Giffin's other books. I recommend this to anyone who enjoys chick lit or books written by Emily Giffin. 4 stars.
