New Delhi, Nov 29 (ANI): A revelation of an affair is a devastating blow to any relationship, but when the cheater blames their partner for creating a situation that "made them" vulnerable to the affair, that usually puts the shock and hurt over the top, an expert has revealed. Sheri Meyers, author of Chatting or Cheating, has suggested that when cheating happens, both partners must take a serious look at their own responsibility and contribution to the downfall of their relationship. Meyers has listed out few reasons why most cheaters say they strayed. Researchers have shown that couples who lead separate social lives are much more likely to cheat than couples who spend more time enjoying common friends and interests.
