So happy that the situation didn't end badly, @tarazkp - you handled it well, and I really hope she was able to move on after school.
I've not watched Baby Reindeer, but I've heard good things about it. I have been stalked by an ex after a very bad break up, and it was really bad for a while. Your point about Facebook and social media struck a chord, as a few years ago, he started following me on Linked In, and it was before you could block people. It totally freaked me out!
