So, the story is that a photographer who has low self-esteem loves one man, who dumps her. Then she meets another man (who happens to be her best friend's brother) and marries him. He is perfect in every way (and he is obscenely rich) and they love their lives together. Then she runs into the first guy (who gets her blood pumping again) and can't figure out why she's second-guessing her relationship with her husband. She sort of cheats with the first guy and then finds out she really loved her husband in the first place, and they get back together.
Now you don't have to read it. I've saved you the trouble.
