Although i acknowledge that this is a Patient/Dr relationship and all that jazz, i dont think its 100% impossible that you could be truely attracted to eachother. Stranger things have happened and people fall in love all the time. If you feel like your reading it right and you want to say something then that is your prerogative! Just be prepared that you may have been massively reading into things and end up mortified.
Im a big believer in love at first sight, you never know!
