Infidelity lecture

After listening to the majority view on infidelity during this weeks lecture, it seems most people treat it with an absolute disgust. Not having experienced this in any way myself, i am still able to look on it with an open mind. Surely, there must be some instances in which it can be seen as morally justified? The example given to us of how a mother, having not had sex with her husband for 10 years due to his depression, sought fulfillment through use of a dating agency. While at first sight this seemed simply a case of selfishness and putting her pleasure before the sake of her family, in fact if we look closer she was doing this for the sake of her family. She mentioned how although she does feel bad for going behind her families back, without this service she would, by now have left her husband and children. This shows us just once instance where infidelity can be used to hold a family together, rather than tear it apart. However there is no doubting the amount of pain caused to individuals through affairs, a pain which i hope many of us will never have to encounter.
