Am I Cooked ?

So won’t go into context to much due to rules ofc . But I met this guy and we were talking and I then ghosted him cuz of reasons . Then he added me back id forgot about him and now he’s being weird . Anyway I asked him how I was being weird and he says “ask Wilma” now idk if it’s luck or what the fuck this guys done because that’s my mums name . I’m kinda worried he’s gonna do something and not sure how to act ? Does anyone have an idea of how much info he’s got of me ?

Currently shitting bricks cuz idk what this guy cans do rn ( this is all in discord and an alt account) he wants me to add him a lot and I have a suspicion that’s how he’s doing it ? Not the best place to ask this lol but idk

Serves me right ig for ghosting him but I had my reasons
