idk he sent fake nudes

so me and this guy are extremely close and have been for ages and we we started talking about stuff what we wanna do to each other blah blah blah I sent stuff he sent stuff back I noticed that a picture looked like it was a Snapchat sticker so I then looked up "dick" for example and saw what he sent me and I think maybe he may have sent me real stuff before but today I felt just betrayed when I saw him sending fake stuff multiple times. and I said hey that looks like a sticker and he completely avoided it and idk what I should say or do.
