I fell for my high school teacher
Why did you fall for you teacher?
Because he was the only one who gave me attention
Just understand that if you are underage, this is illegal for you and your teacher to have a relationship. It is fine to have a crush, just realize that it may have to remain a fantasy until you are older.
Do you have a problem with who was right and who was wrong?
Well your teacher should not be pursuing a relationship with a minor. No emotions are wrong however, just how you deal with them can be. Don't be too hard on yourself!
