Query: Are you kidding me? I HATED this character

The main character of this book is by far the most unlikable protaganist I've ever come across. She sleeps with her best friend of 20 years fiance and doesn't feel guilty about it!! And she whines incessantly about how her friend is so lucky and how she's been outshone by her all these years. Well, maybe that's because you're an f'ing loser, sweetheart. The only reason I finished this book was because I was hoping she'd meet some terrible fate and end up even more miserable.
