This is just another iteration of "stand up when i leave." Now its "im gonna say i love you every time i leave." Its very - whats the word? - acty-outy. He is not a Ken doll.

"Try and stop me" seems to be the implication here, not "help me i cant stop myself." Thats where the ethical line is drawn. He must not choose to join you in your folly. And of course he does not wish to abandon his patient.

Maybe i am reading it wrong.
