“I want her to have a happy life but this relentless harassment is taking a toll on me.”
Why are you trying to be a saint? She doesn’t care about you or your reputation, so take legal recourse and let her learn her lesson and face consequences for her actions.
If she’s most probably under the impression of getting a woman pass then it will break he delusion.
Today’s times are different, protect yourself as very few or even no one will come to rescue you or your family’s reputation.
