What can I do ?

I know it’s wrong now but in the moment I thought it was a smart idea bc I liked the guy. Alright so abt a year ago I was talking to this guy and we exchanged nudes.

Yeah Ik . We were playing a game and it was a dare. He said he wouldn’t do anything with them and I believed him. A year later I’m over him but my guy friend sent me my own nudes . Then my best friend said that she just saw my nudes . And I’m just at a loss bc Ik he shared them .

So any suggestions on what I can do? 😅
