kill them /j

okay that situation kinda sucks, idk what kind of person ur ex was but im hoping they're not someone to just leak n00ds. if u trusted them while u were together and u didnt end it on bad terms, i dont think there'd be any reason to be afraid. in fact, if u broke up in peace, u could maybe even just hit them up and ask them to delete them or just generally talk about it w them.
if things ended ugly, depending on how ugly, u could still talk to them. if thats not possible then ig u should just keep ur legal rights in mind yk. after all leaking someones n00ds is illegal lol obviously thats probably not gonna help completely IF they do leak them but thats all i got for u rn. if u ever wanna vent ur heart out about it tho my dms (but also my rs if u wanna stay anon) are open to provide emotional
support (or help get rid of the body if u settle for the first option /j)
