What Is The Name Of This Film Noir Movie?

It is an old movie, probably a black and white. It's about a woman who falls in love with and marries a man she subsequently suspects is plotting to murder her. It seems as if she is right but in the final scenes, when she thinks he is trying to kill her, he is actually trying to convince her that he loves her. It is NOT the movie Suspicion. It's sort of like Sudden Fear with Joan Crawford and Jack Palance. HELP!
