The rest of the title is: Facing Adversity, Building Resilience and Finding Joy.
I don't have a copy of it (returned to library), so I'm going by memory. (I hope this helps, psychmom!)
I found a lot of understanding in this book about how it feels to face a sudden trauma. It was death in Sandberg's case, but discovering infidelity was definitely a trauma for me (and was a death of who I thought my husband was).
There is a progression in the book from the discovery, the tendency to self-blame and how to handle that, understanding why other people have a hard time knowing what to say or do in response to your trauma, ways to keep living your life, a section about the kids and how to help them with their grief (as far as I know our kids don't know about the A, but not sure), giving yourself permission to be happy.
I especially learned from the 3 P's (personalization, pervasiveness, permanance) and how managing those are key to healthy recovery, and the section about post-traumatic growth.
Sandberg's experience is there throughout, but there are also stories about people who have survived different traumas. I think there is at least one that involves infidelity, but I think the whole trauma aspect very much applies to infidelity.
Books and podcasts have been so helpful to me in this journey, since I have not found safe people to talk to besides IC,SI and somewhat MC. Recently I even managed to finish a couple of novels! That is an accomplishment after 2.5 years of post A despair (we're getting better at R lately - I think - don't want to jinx it by saying so! ).
