Does anyone know the title of the movie in which a father has an affair with his son's fiancé?

Also, I'd like to find the title of the movie in which a handyman falls in love with a single woman. She gets very ill with a fever and he carries her and puts her in the bathtub to bring down her fever.

Thanks!

Bella, off the top of my head, the first plot you mention reminds me of the Jeremy Irons/Juliette Binoche movie, Damage (1992). See this link for plot summary:
Damage (1992) (http://imdb.com/title/tt0104237/)

The second one sounds so familiar but I need to give it some thought. Someone else here might come up with it before I do.
