Yes. It takes time and work, but experts are pretty unanimous on this one. In her book The Monogamy Myth, Peggy Vaughan estimates that 60 percent of husbands and 40 percent of wives will have an affair at some point in their marriages. That’s no advertisement for straying — but the news is good for couples hoping to recover from devastating breaches of trust. The offended partner needs to make the choice to forgive — and learn to live with a memory that can’t simply be erased. Infidelity is never forgotten, but it can gradually fade into the murky background of a strong, mature marriage.
