Co-worker putting out quite the vibe in the office

DEAR ABBY: I work in an office with a man who has expressed an interest in me in various subtle (and not-so-subtle) ways, including winks. I have also caught him staring at me with intense longing. We communicate well, and he has told me I have influenced him. We are both disciplined, determined and accomplished men. I envy him for his easy smile, his self-confidence and his effortless, universal appeal.
