Wow, what a terrible situation, I’m sorry you’ve had to go through that. It never ceases to amaze me at how brutal and vindictive people can be, especially online. Does she even know how much this has hurt you? I could imagine someone with poor empathy making a move like that in an emotional flurry one day, then never giving it a second thought in the months and years to come. Meanwhile, you continue to suffer the effects, psychologically and socially. Horrible.
