My Patient's Secret Admirer

I've been married to Sarah for ten years now. We have a great relationship and I wouldn't change it for anything. But lately, there's been something bugging me, gnawing at the back of my mind. A few weeks ago, I noticed an unusual spike in visits from a patient named Emily. She had never seemed particularly interested in medical advice until now. It's not just the frequency, she seems more preoccupied than ever during her visits, shifting uncomfortably and looking away when our eyes meet. I started thinking maybe she has some kind of health issue she's embarrassed about but can't seem to address. Then it hit me: Could it be that she’s developing a crush on me? The thought sent my heart racing, how could I feel such an intense mix of attraction and guilt? This isn’t just about medical ethics; it feels almost like betrayal to even entertain the idea. Is this something normal, or should I really be concerned for Emily's well-being? Should I talk to her directly, or would that cross a professional line? Any advice on what’s right here?
