I can imagine why Perel is unpopular among betrayed spouses. That's because she brings a different perspective on infidelity, which does not automatically label the party who cheated as the sole responsible for the couple's situation. Most betrayed spouses are so hurt they can't see any other perspective than pain, disgust, and, in some cases, even revenge. But Perel also says that infidelity can be a ground for improving a relationship because it brings to the surface issues which otherwise would be left unsaid and pushed under the carpet. She brings evidence from therapy that couples can recover from infidelity because infidelity is just a symptom and is not the root cause of the couple's issues. As some other readers said, nobody cheats because they are doing great in their relationship. In my case, my husband still believes our marriage is normal, and lack of affection is just something I need to deal with because "I'm too needy" and intimacy is reserved just for when we have sex. We live in two different worlds, yet we have a functional marriage. How do you fix that?
