For couples, the answer is yes, with work.
Tempting as it is to ‘sweep it under the rug’ and carry on, that’s a dangerous strategy — because the unresolved anger tends to turn into contempt, which is corrosive to relationships. Whether the affair is emotional or sexual, the results are devastating, and both partners suffer.
To recover, both partners need to commit to telling the truth, looking at the circumstances surrounding the affair, turning back to the relationship, and rebuilding trust. This work is best done with the support of a couples therapist.
I’ve worked with many couples who have gone through an affair and come out the other side with a renewed commitment and deeper relationship.
