Emily Giffin's character, Rachel White, in Something Borrowed goes through just that.
While modest and genuine good girl, Rachel is indeed ecstatic for her best friend, Darcy, she wants nothing more than to forget about her birthday, curl into a ball, and wallow in her own misery. All she ever wanted was to have a job that she loves with the man of her dreams by her side.
As Darcy has a sensational PR job and a gorgeous diamond on her finger, Rachel is left in the dust still pining away for her dreams in her single and job-hating life.
Although Darcy has thrown Rachel the best 30th birthday party that anyone could ask for and inviting millions of friends who are thrilled to celebrate with her, Rachel is still missing the two things she wants in life.
So when Darcy becomes too drunk to last any longer at the party, Dex, her husband-to-be, suggests that she call a cab to carry her home. While the party slowly dies down and everyone has left, Rachel is left alone in the bar with Dex.
They chit chat about simple things: job, friends, life. Somehow neither one of them mentions Darcy or the upcoming wedding.
While Dex and Rachel fall into a cab to head their separate ways for the night, Dex suggests one more bar, then another, and another. . .
Before she knows it, Rachel is in her apartment falling into the arms of betrayal and her best friend's fiance.
As the fresh affair gains momentum, Darcy decides to set Rachel up with Marcus, Dex's best friend, thinking that Rachel will greatly appreciate finally having a man in her life. Naturally she has to suffer through countless dates with Marcus in order to please her best friend, but unbeknownst to Darcy, Rachel seldom misses a night with Dex.
Something Borrowed is a great read involving friendship, betrayal, and more than one secret romance. This is sure to be a book you won't be able to put down, and you don't have choose sides to enjoy it. First in a two-part novel, this story is real and certainly displays that the line between right and wrong is just a little fuzzy sometimes, but it's always better to do what's best for you.
