“All marriages are alike to the degree that confronting an affair forces the couple to reevaluate their relationship, but dissimilar in how the couple lives with the legacy of that affair. I already knew the marriages I was tracing in these follow-up interviews had survived; now I wanted to assess the quality of that survival. What were the useful shock absorbers that sustained the couple? Did they think that therapy had helped?

Specificities notwithstanding, I identified three basic patterns in the way couples reorganize themselves after an infidelity—they never really get past the affair, they pull themselves up by the bootstraps and let it go, or they leave it far behind.”
