Found out my ex/ bd still has my nudes

Long story short in my healing phase I post the trauma I went through in our relationship in a close friend list, someone screenshot it and sent it all over. Now he’s mad and saying that’s why I wanted him to delete my nudes while we were together etc. then he went on saying he still have them on cloud in a backup folder, but he won’t post them bcz he doesn’t put things online like I did.

I’m furious but there’s nothing I can do as I’m not capable of making him delete them, but he’s in a whole relationship and still has my photos. (My face isn’t in any of them by the way). But why would a man keep naked photos of an ex he’s on bad terms with?

Only pics I have of him is with our child.
