I'm having a problem with a girl at work. She's adorable, wholesome, and has made it evident that she wants me to ask her out. Although I would if we met in the outside world, she's my supervisor's secretary so that's never going to happen. My career means far more to me than some office fling. She hasn't seemed to take my gentle hints that it's not going anywhere. How do I make it crystal clear without hurting her? I don't want a situation where she's ignoring me or giving me weepy eyes every time I pass her desk.
