Hey there, Zara!

I agree with the other replies that writing a note is a good way to go about this. It can be easier than saying it face-to-face, and you can think more clearly about what you write down. I also doubt you freaked him out. It may seem like he's avoiding you, but he could just be busy or stressed out, as teachers do have rather busy jobs which involve contact with a large number of people.

I wish you the best of luck in telling him! Feel free to send me a message if you need help with anything. Take care!
