Video: Rethinking Infidelity--A Talk For Anyone Who Has Ever Loved

"Affairs are way less about sex and a lot more about desire--desire for attention, desire to feel special, desire to feel important. " - Esther Perel

In this TED talk, therapist Esther Perel gives a fantastic presentation on infidelity that is rooted in both scientific research, as well as her own clinical observations. She addresses a number of interesting questions, including: Why would someone who is happily married and loves their partner deeply end up cheating? Why do affairs hurt so much? What can a couple do when an affair is exposed to heal and move on? As hurtful and destructive as affairs can be, can any good ever come out of them? Perel comes to some provocative conclusions and challenges us to think differently about infidelity. Check it out and weigh in with your thoughts below.
