The revelation of a cheating spouse is an understandably devastating event in a person's life, and not one that's easily recovered from. Months - if not years - after the affair, couples find themselves dealing with fallout from the infidelity. One of the principle concerns that arises is whether the offending partner is capable of staying faithful.
The old adage says, "once a cheater, always a cheater," but is it true? Writing in her blog on the Psychology Today website Dr. Diana Kirschner says that's simply not the case. Granted, there are some people who perennially cheat on their spouses, but she attests that many more couples have been able to work their way through these crises and emerged with healthy, functional relationships.
In her post, Kirscher points to a few key signs that show a commitment to improving the situation - chief among them cutting off contact with his lover and showing a renewed devotion to you. He may even go so far as to recommend seeing a therapist together, but it may be on you to make the initial suggestion.
If you're dealing with an affair, your skepticism is absolutely warranted, but don't sabotage your recovery by assuming things can't get better.
