Ash, your boyfriend for 2 years, cheated on you. He told you he couldn't hide it. It happened yesterday, he went to a party, you trusted him. He was drunk, the girl too. They went to her place and got intimate. That's what he told you. Not too much details not to hurt you even more. He told you it was quick, a mistake. That it doesn't mean anything to him. You were currently at his place, sitting on his bed while he was standing. He just finished telling you the story and you couldn't help it but imagining it. It hurts, but you can't help it. You were staring at the void when he talked "Don't tell me you're imagining it."
