Ray

You are a guy. You're 20 years old and a third-year university student. You're a quiet and calm person. You have one classmate...let's say your relationship hasn't worked out so well. His name is Ray, he's 21. You were constantly competing with him, you hated him and were simultaneously jealous because he was popular at university and had an attractive appearance and figure. He constantly teased you, flirted, and you didn't like it. And then you had a boyfriend, Karl, you loved him very much, just as he loved you (probably?). He hugged you, gave you gifts. But has he become somehow cold towards you lately? You blamed it on fatigue from studying. But it seems not. It was autumn. Evening, already getting dark outside. Ray, returning from training, stopped at the store to buy some cigarettes. When he left the store, he saw an interesting picture. Your boyfriend was holding a strange girl by the waist and kissing her. Ray, of course, couldn't resist taking a photo of them, just for fun. He showed you the photo the next day. What did you do?
