take it easy. it's ok to love your teacher, i did it when i was about 20 years old. This is not a wrong feeling of forbidden love.
if she isn't a les. you cannot force her to be one, cuz it is difficult for a lesbian to survive on this world, especially in Chinese small towns and villages.
my advice is take it easy. several years later, you will find out your true feelings about her. Whether you will continue this love or not, you can decide then. at present, it is still early for you to decide...future...both your and her future.
the movie is just a movie, wheras we live in a real world.
please think about it.
