I wanna figure out how ratted me out

Um so context, basically after YEARS I managed to cut off a toxic friend. But the only reason I was able to cut off that friend was cuz someone took a screenshot of my WhatsApp status abt them, larping most of my interests.

And I used that as an opening into finally cutting them off, but the problem here is that when I made that status in the first place, I hide my status from them. WhatsApp allows u to manually control who sees ur status & who does not. So b4 posting that status, I selected the toxic ex - friend & certain ppl who I knew were definitely gonna tell this toxic friend abt my status, from seeing my status in the first place.

I absolutely have no idea who it is, all the ppl who viewed my status either hate/dislike this toxic ex friend too, or don't even know that the person even exists, since I like keeping my social circles separated from each other.

Ik that my issue isn't rlly that deep, but what I want from this is tips and advice to try to find out who told that ex friend abt my status so I can cut them off aswell.
