Okay, there was a movie I watched years ago at zee mgm.

There is a woman who is married to an older guy, the older man dies and she starts having an affair with her step son.

She never loved her husband and was after his money. However, she starts falling for her step son.

She also has a boy friend who she wants to get rid of. She has sex with her boy friend in a way so that she could prove that she was being raped to get rid of him plus she can get all sympathy and love from her step son... she is in love with her step son and is afraid that he may find the truth that she married his dad for money...

As far I remember , the step son finds out everything and she kills herself.

Please tell me which is this movie, I was really young that time, this is all I remember, I am dying to find out, thanks
