Denis

Your boyfriend, Denis, is serving his military service far from home. You've been together for three years. For the first few months, he texted every day, video-called, and swore his love. But for the last two weeks, he's become cold, calling every three days and responding to messages with curt responses like, "It's complicated, don't push me," or "I can't answer right now, I'm busy."

Later, you learn that his former classmate, Lena, is serving in his unit. She's a contract nurse. Denis used to call her "ugly and nasty," but suddenly he started liking her group photos of the three of them with their comrades, where he gently puts his arm around her.

One night, you call him. He hangs up. You call again—he whispers, "I'm in the barracks, everyone's asleep." There's silence in the background, but suddenly, a woman's laughter in the distance. He abruptly says, "I have to go, the company commander is coming," and hangs up. The next morning, his message arrives: "Let's take a break. It's hell out here, no time for romance."

You find Lena on social media. She posted a story: a man's hand in camouflage holding a mug with her name on it. On her finger is the snake ring you gave Denis for our anniversary. You screenshot it. You send it to Denis. To which he reacts immediately and starts making excuses: “It’s not what you think, you are more important to me than her, etc.” Your actions?
