Hi, same thing happened to me when I used to fancy my (male) french teacher. You cant really do much- having said that I used to act really stupid so he would come and help me alot!!!!!. Kinda opposite to the other suggestion of try hard
My friend from a (different school) fancies one of his teachers and acts all depressed around them, so she thinks hes got serious family problems and 'supports him' but that’s sort of exploitative i think.
