This is long book. It spends a lot if time introducing the characters. There is a good reason behind the introduction but it took time and I think made the affair even more difficult to accept. I've never bothered me when reading a book where either partner had an affair until I read this book. It just didn't work for me. Sabby (Sebastian) cheating on Julia was hurtful and it lasted for a year. So I guess at the end Sebastian finds his true love but how many others has he ruined. He's a selfish prick. So is there really a happy ending?
