Her Costly Affair is a 1996 American made-for-television thriller film directed by John Patterson.
The film was initially to be released as Consensual Relations, until lead actress Bonnie Bedelia had it changed.
Because she is not getting a lot of sympathy from her husband Carl and teenage daughter Tess, she isn't bothered with the special attention of Jeff.
She immediately ends their affair, but he isn't willing to stop seeing her and shows aggressive behavior.
She eventually finds out that the death of his girlfriend Ann was a suicide, although Jeff was the prime suspect of murder for a long time.
