is this crazy or am i overreacting??

So I used to date this guy back in 2014 and we dated for 3 years, and throughout the relationship we sent eachother nude photos which was all consensual and he would save some of mine for “later use” kind of thing, we broke up because we both just fell out of love and we remained neutral (ie we didn’t block eachother but we unfollowed eachother but still kept each other’s number bc i never thought to delete it) but then he texted me recently that he still has those nude photos of me...my face isn’t in any of them so it doesn’t scare me too much but it does freak me out that after all these years he still has them, and he also told me how he’s in a new relationship...but still uses my photos...has anyone else ever dealt with something like this?
