Hi guys,I would like to remember the title of a movie I watched since a long time ago. It's about a woman who kills her husband and burns the house when she discovers he has an affair, then she moved to another city where she pretended to be teacher in a high school, and in that school she makes a relation with one of the students and later the father of that student fall in love with her and things get more complex when this woman kills the teacher that used to work before her in that school. In the final scenes the woman tries to kill the student but she falls from a high building and the student thinks she died but when police checks they don't find her body and later it appears that she runs to another city and get another job in another school.I like to remember the title of the movie or at least the name of one of the actors/ actresses in it please
