I don't want to sound like im trying to be an expert or anything but after reading all of this post something that came into my head is...
Whatever situation the relationship is in a women will always have an open door that allows men to trigger attraction. Every women is different so some doors will take more effort than others and to make her think about cheating you would have to trigger her attraction to a higher level than the guy shes in a relationship with.
So in a sense if you can make her feel x amount of attraction for you then she will cheat
.... ("x" being however much she would need)
