Hi. Maybe I can help. I would be cautious in assuming that a medical professional may be expressing a romantic interest in you. I encourage you to keep a healthy boundary. It is easy to confuse his posture or bedside as flirting-- especially if you are hopeful that it may be more.
Medical professionals have specific boundaries that prohibit romantic relationships. Maybe part of his success has been that he is able to join with patients and attend to them. I would accept his medical advice, but keep the boundaries of patient and Doctor. I apologize if that is the news that you don't want to hear, but ethically, it is the most truthful answer I can give.
You are welcome to provide more information if that is helpful.
