I'm looking for a movie that a wife has hallucinations of a woman that is in her house. I don't remember why but she is not supposed to get out of the house.

The wife realizes that the woman she's been 'hallucinating' with is actually real, and it was all of her husband's plan so that he could sent her to a mental institution and keep all of her wife's money.

Something like that happens in this film:

Could be "Images" (1972) Images (1972) - IMDb (http://www.imdb.com/title/tt0068732/)
