Dodged a major nuke

I'll keep this brief, but this summer a Pick me tried to pimp me out to her disgusting pig of a scrote best friend and literally tried to trap me in an apartment with him. They've been trying to manipulate me together for years before that to make me "like" him, when this pig has a decade long history of bad behavior towards me and people I care about but is obsessed with getting me to bed him and his friend. The predatory manipulation became intense this summer when she pretended to play a match maker with good intentions. Let's just say a game of broken telephone happened and even when this scrote was supposed to pretend to "like" me, he could not keep the mask on at all, it was paper thin. Thanks to FDS I saw through everything, every neg, insult and comment about my physique, projection and his attempt to make him seem like a prize that I was supposed to chase and impress. When it all came to an end and it was clear the manipulation hadn't worked he was practically begging to hook up with me(after said pick me had done something perverted to me that he requested). Now however the pick me that was speaking for him/telling me the messages he was sending her, did say that he'll try to run into me at a mall I frequent in a city I visit and he's also watched me several times in the city when I wasn't aware of it. He thinks that I may finally agree to a conversation with him because I'll have "forgotten" everything he's done. -- It's annoying and I don't want to give up my mall, but what should I do if he confronts me?
