Hi Anna,
Thanks for writing to Alterheros. Ultimately, it is only you who knows whether it is wise to speak to your teacher about having a crush on her. One thing that you might want to think about though, is that there is an inherent power imbalance in the student/teacher relationship, and that this might play into any interactions you have with her. She has her position as a teacher to consider, and this may affect how she responds to you confiding in her. Also, you may want to think about where this person is on same sex attractions. So, I don’t have a clear answer for you, but hopefully I have given you a few things to think about when making a decision about whether or not to talk with you teacher.
Best regards,
Andrea, AlterHeros
