It's basically exactly what the title said. I met her for dinner yesterday and she was easily 50 pounds heavier than her photos. So I left immediately because she wasted my time and I wasn't attracted to her at all because of the weight gain. Then I sent her a couple of messages, saying stuff along the lines of 'fat pig...' (I didn't use any slurs as there not in my vocabulary and I didn't even call her a b*tch) and talking about how she wasted my time and needs to lose 50 pounds or else no man will find her attractive. Now she's found my specific job and is threatening to email my boss with what I said. What's the best way to avoid this?
Should I try to see if I can get her to state that she'd take $ to shut up and then have my lawyer older brother write a letter about blackmail? Or is there another better way? I care about my reputation first and foremost and don't really regret what I said as she wasted my time and catfished me, but if I have to fake repentance I could do that. Some 'last resort' steps I could think of would be trying to leak my information on the dark web so I can say I was hacked / it was a fake profile or claiming that I'm bi?
