A young girl is walking home from school with her chello and a man drives beside her it's raining and tells her to put it in his car so it doesn't get wet. They end up dating even though he's significantly older then her, he smooth talks her parents into letting her go out with him, she looses her virginity to him and she finds out he's an art thief, she's reluctant but stays, he asks her to marry him and she finds out he is married. I don't know the actors, but love the movie made probably late 90's early 2000's. Need this movie title. I believe its like lesson or something. Please help thanks!
