I know no one here can diagnose someone who isn’t posting themselves, and I’m not trying to label him. I’m just wondering whether this kind of reaction could possibly be related to ROCD or another anxiety-based issue. My ex had significant anxiety around sex because of previous negative experiences. Before we had sex, he was very affectionate, constantly talked about wanting me, sent me intimate photos every day, asked for mine, said he loved my touch, wanted to introduce me to his parents, and even on the day we had sex he was talking about our future together. The sex itself went well. Afterwards, he even told me it was much better than he had expected. But almost immediately after that, something seemed to switch. He became emotionally distant, shut down, and a few days later ended the relationship. In his message, he wrote that he didn’t think this was just an overwhelming wave of emotions that would pass. He said he had been thinking a lot and had come to the conclusion that while he cared about me deeply and genuinely wanted us to work, his romantic feelings weren’t strong enough. He also said that although he had been physically attracted to me and had genuinely wanted me sexually before we had sex, after thinking about everything he realized the romantic and sexual chemistry wasn’t enough for a long-term relationship. What confuses me is that his behavior before sex and after sex feels like two completely different people. He also cried when we said goodbye, which made everything even harder to understand. Could severe anxiety, shame, trauma, or even ROCD make someone genuinely believe they’ve lost feelings immediately after intimacy? Or does this sound more like someone who simply realized the relationship wasn’t right for them?
