One True Loves

Gave this one a read because I saw it had a movie trailer and I quite like the way TJR writes her characters. But is this one of her older books or something because this is NOT IT. The plot centres around the main character realising her dead husband is alive 3 years later, and her having sex with him while keeping her current fiancé on the back burner. And then he's like totally cool with it, she gets back with the fiancé and has a happy ending?? This could have worked if she didn't get either guy in the end, I think I just hated how she basically cheated on her fiancé but there was absolutely no remorse or consequences for it.
