My female friend and I started having intimacy few weeks after we met. We weren't dating; we were just two adults who occasionally slept together. Shortly afterward, she was diagnosed with an infection, but she never told me. She took her medication, recovered, and we continued our sexual relationship as if nothing had happened. A few weeks later, she called me sounding angry. Friend: “We need to talk about something.” Me: “What's wrong? You sound upset.” Friend: “Have you noticed anything unusual about your body lately?” Me: “No. Why are you asking?” Friend: “Because my symptoms have returned, and I don't understand what's happening.” Me: “What symptoms? What are you talking about?” She went quiet for a moment. Friend: “Do you remember when I told you I wasn't feeling well a few weeks ago?” Me: “No, you never told me anything about that. What happened?” Friend: “I went to the hospital. They diagnosed me with an infection, and I took medication. I thought I was fine, but now the symptoms are back.” I was surprised. Me: “Wait. You were diagnosed with an infection, and you never told me?” Friend: “I didn't think it was necessary. We weren't in a relationship, and I handled it myself.” Me: “But we've continued sleeping together. Don't you think I should have known?” Friend: “That's not the point right now! I need to know if you've been with anyone else.” Me: “Why would you ask me that?” Friend: “Because I think you gave me something!” I couldn't believe how quickly the conversation had changed. Me: “How can you accuse me of giving you an infection when you never even told me you had one?” Friend: “My symptoms disappeared after treatment. Now they're back after we've continued having sex. What else am I supposed to think?” Me: “You could start by telling me what the doctor diagnosed instead of accusing me of something you haven't proved!” She ended the call angrily. I sat there wondering how a casual relationship had suddenly turned into an accusation about my health.
