Someone told me about a movie I want to see now but didn't know the name. In it there are robots people can purchase to live with them like if they are lonely. The more money they pay for one the more life like and more intelligent they are.

The main lady in the movie gets the highest up most intellegent one possible and he becomes like her soul mate. Somehow she gets an upgrade for her robot that isn't out yet due to testing. With this they start having sex and then becomes controlling of her. At the end to get away from him she swims across a lake or something.

IMDb synopsis:
In the near-distant future, a female romance writer is planning to write her next book in a remote mountain cabin. A friend convinces her to bring along a "companion", a nearly-human Android to cook and clean. She settles on a male companion named Geoffrey. Bored with some of Geoffrey's behavior, she tinkers with his programming: first his personality then his sexuality. Real trouble comes when she gives his mind access to "random data".
