Looking for a movie. Movie Description: Poor, beautiful woman marries rich man, who is possessive and abuses her. She has a great fear of the water. Woman plans her escape; on the sly, she learns to swim. When husband takes her on a boat with friends, she fakes her death and "falls" over board. Search party looks for her, but can not find body. She swims ashore, takes minimal supplies from house; starts a new life. Husband thinks she is dead until the womans' swim teacher calls to offer condolences. Husband searches down wife and then tries to kill her.

Sleeping with the Enemy (http://www.imdb.com/title/tt0102945/)
