The friend is not innocent in this scenario for three reasons: (1) she continued to engage the man after learning that he was married; (2) she didn't approach the wife to settle matters after learning of the rumors; and (3) she went out on a date with a married man. Had she ignored his antics after learning that he was married, the onus would've remained on him. Just because someone calls your name, rings your doorbell, dials your phone number, etc., it doesn't mean that a response is required. Since she repeatedly engaged him whenever he sought her out, she has to share some of the fault. Additionally, once she got hint of the rumors, she should've maturely discussed the issue with the wife instead of haughtily dismissing her. Doing this would've also kept the onus of guilt on the husband; plus, it would've shed light on her side of the issue and most likely have resolved things in a satisfactory manner. Number three is self-explanatory. Unless an individual is a baseless ho, married men are always off the table. The end. However, if the friend continues act as a blame-less victim intent upon seeking revenge instead of humbly accepting her part in this fiasco and working towards a mature solution, she may very well find her self nursing a black eye and several contusions while on the unemployment line.
