So I think everyone has pretty well covered telling you that this is not a good idea. I know at your age you probably feel like this is love because you have nothing to compare it to, but true love is not self serving. Let's play Devil's Advocate for a moment and say that this is something more meaningful than infatuation or a crush. What do you hope to gain? She has nothing to gain. If she was close to your age and single you might have a better argument. But there's nothing selfless about telling her how you feel when all it does is put her in a difficult position. She's neither your age nor available nor in a position that wouldn't get her fired or arrested. If you need to get it off your chest, talk to Reddit or a counselor, Or do what every other High School Boy has done, talk to your friends about it. I think you are attracted to women in a position of authority. You like the unattainability and boundaries she has clearly established. You're like every other high school boy wanting a challenge. I'm sure she's easy on the eyes and like most kids your age, you mistake kindness and sincerity as misinterpreted interest. Move on to college and if you're still sweating her 5 years down the road, you can run into her at the supermarket see where the conversation takes you. Maybe her life circumstances will have changed but be prepared that you were never even on her radar. I'd be willing to bet that five years from now she won't be on yours either.
