A few things need separated out
the name calling & unpleasant tone (although to be expected) adds nothing. It’s an indignant background noise at best
the ow having the relationship with the MM isn’t necessarily waiting,hoping and scheming that she’ll get picked, or she’ll be the next wife. Plenty women date MM for sex,because they like it because they want to. Women don’t always seek or want marriage house ,kids as the culmination of a relationship. Some women are happy enough in a relationship that’s based on the sexual chemistry and the here and now
Being the ow can in no way be equated to homicide,harm,and dysfunction. Nor can an OW be wholly held accountable for the impact of a marital affair. Takes two. Two are responsible and accountable
Women who like sex,and male company are always demonised in some way. As the culmination of so called proper relationship is purported to be marriage and stability. The OW and the errant husband pose a tangible threat to the family and deviate from typical women good girl roles. so the OW are a scary threat,to be despised and pilloried
i think affairs are nuanced and essentially come down to opportunity and volition. Depends on the personality and behaviour of the individuals
I don’t think folk who have affairs are other,or really bad they are brothers/sisters,friends .colleagues,acquaintances making potentially dubious choices.
