Sounds a bit obsessed and stalker material to me.
He definitely sounds capable of plenty of irrational hatred, that's for sure. I'm also really sorry you had to go through such a vile experience, LouLou, and I hope you're okay now. Don't listen to his bullsh*t about finding things out about you - he obviously is far more concerned with frightening you to death than with doing anything else. And if he starts trying to contact you again, and threaten you, you can go to the police.
God. What an absolute psychopath. Reciting your advert to you, seeming obsessed with informing you of how "rude" you are? What an entitled scumbag. Who the hell would think, "Oh, that person doesn't seem to want to see me, I'll trick her into seeing me so I can try to force her to do services she hasn't consented to?" Disgusting. If you think you hear from him again (even if he sounds like a 'changed man'), report him immediately!
