I found out she follows my partner on IG and somehow knows all about me. I have no idea how she found her but she claims that "she sees my partner all the time, and that she will talk to her next time"

I guess in terms of evidence she has texts between us when I made bookings (she's a private)

Before blocking her, I sent her an article of the SW being charged for harrassment and blackmailing clients. Hopefully she will take the hint and back off.
