Background helps. Women could NOT choose a husband - they were married off by their families. So, the woman at the well was not living with yet another husband supplied by the family, but presumably with someone she loved. Not condemnation by Jesus - the opposite in fact - she, the foreigner, the "heretic" became the first cross-cultural missioner in John's Gospel! No ethical comments are made of the issue of whom she was living with - Jesus' insight is the occasion of the woman acknowledging Him as prophet.
