Seems like your using humor as a defense mechanism to prevent transference or a connection with her, how's that workin for ya? I do similar things so don't get offended. As for the "creepy" comments on following her home and stuff, it seems like she knows you well enough to know your just joking...but in her profession I would think there is a healthy fear of those things so IN MY OPINION , I'd tell her exactly what you said here. That your fear of a connection is where all this stuff is coming from. Just talk to her and be honest, this will alleviate your fears and clarify your prior statements.
