Engaged but Tempted by My Student's Intensity

I never thought I'd write something like this, but here I am. Engaged to be married next year, with a solid career ahead of me as the English teacher at our local high school. Yet lately, one particular student has been on my mind in ways that feel... wrong. She's an incredibly talented writer and thinker, always eager to dissect literature beyond its surface meanings. Her passion for words is captivating, and I've found myself daydreaming about her intellectual fire more often than I'd like to admit. It's not just the conversations during class or after hours when she asks me for extra help, it’s the way her eyes light up with understanding when we discuss a difficult text. And it hits me how unfair this feels, that I should be so attracted to someone who could potentially become my student in a different life. I know there's nothing real here, and I'm doing everything I can to keep my professional boundaries intact. But every time she reaches out for advice or feedback on her work, it brings up all these intense feelings I try to suppress. It’s lonely keeping this secret, even if I’ll never act on it.
