I would guess I saw this movie about 5-7 years ago, but I don’t think it was a new movie at the time. It was a movie in English, and I saw it on tv. I think it was on Lifetime or a similar Network.
There is woman who lives with her boyfriend/husband, they are not very well off and the husband is abusive. His friend is quiet and creepy, and she gets him to help her kill her husband and escape. I think she slept with him to get him to do so. She goes and lives with a rich guy she has been secretly dating, a doctor or a professor. He ends up getting arrested for the murder, and she goes back to her home. The movie ends with her in a big field with her dead husbands friend (the same one who helped kill the husband), and she realizes she’s in love with him.
