I did not like the behavior of the main character, who repeatedly cheated on her husband and considered herself the victim when he and her children were angry with her because of it. I had no sympathy for her and found the plot unbelievable.
Imagine a life that works solely on this premise: Unforeseeable things do happen, and it is possible to be shaken by them. You have considered yourself happily married woman for some time, have even boasted to those closest to you that this is the case, and then you spen an hour with the man whose words and touch do the sam things to you that you remember happening when you were a teenage falling in love for the first time....
