In my clinical
opinion, many adolescent girls have crushes on teachers. The girls are
especially vulnerable to those teachers who are younger than their
parent and certainly a little older then they are. I call this
attraction "prestigious attraction." The girl is enamored with their
teacher whom they believe is smarter, and more worldly then their
parents. They envision this person as the Messiah and the one who can somehow take them away from their dull and pointless life.
This relationship can be especially dangerous if the teacher has a neurotic need to be admired and "adored." Perhaps because of their own neurotic turmoil that is present in their life, they look to this vulnerable teen as their own way out of their dismal crisis. The teacher and teen may then fantasies and they create a relationship built on psychopathological needs.
If the teen is especially a moderate or sub-dominate individual, she will be more highly susceptible to the influence of a more dominate and charismatic "leader." The result may lead to tragic consequences for all.
