I'm lost as to where in your post, the person got the sexual harassment part.
You wrote that unlike a workplace, this isn't a place you are required to return to.

I think it is great that in your other replies on pc, you are tapping into things to talk about with your therapist.

Of course you were angry, you were out for an evening and became a sexualized object.

About the response from wherever else that was, sometimes others have their own agendas and biases.

If the other place was about wellness, maybe she was tough loving you from a perspective of not wanting to see you become as she imagined(care of internet) as displayed by book choices? Dunno.
