The private nature of online affairs may make them less painful for the betrayed partner as well.
Consider this reaction: Just as casual sex is not necessarily inherently harmful, neither are online affairs.
But they may be so when participants are also involved in another primary offline relationship, because of the harm imposed on those partners.
When people do Hi, I'm Damian and I been dating a wonderful woman same age as me for about 5 monts. My phone broke, so my girl gave me one of her old phones.
Without knowing she didn't erase any pictures which were all shared with her icloud account.
Thus, people may agree not to develop a relationship, permitting themselves only virtual one-night stands, or an uncommitted affair, or a promise with a partner to tell each other about each online affair.
