None of the reviews mentioned this movie being based on true events; a noteworthy fact given the disturbing storyline... The film is definitely not for everyone. It's about deeply troubled people & is VERY dark & very cold, made even more so by the meticulous art direction, camera work & editing.
The cast is terrific, with a heartbreaking performance by Maria Bello who tackles her character with perfect emotional tone and tempo. It's a tough role precisely because it's so disturbing, and if overacted or otherwise played wrong, the character could become unlikeable, maudlin or self-indulgent. Bello manages to be none of these things.
I didn't find the sex scenes gratuitous, or as one critic called it, "S&M soft-porn". In fact I felt the scenes were appropriately restrained. And there were many tender moments & much pathos throughout the film, including in some of the s&m scenes.
As for the question of why Nancy simply didn't leave the marriage, she herself explains this when confronted by Louis with the same question. This is not the story of a woman with normal problems, marital or otherwise. This is the story of a woman who as a child was sexually abused by her uncle for a long time. And her mother exacerbated that emotional damage by blaming Nancy for the abuse. Typical of many sexual abuse victims, Nancy translated the abuse into "being loved", which compelled her to long for it in subsequent relationships. The therapy she finally seeks is too-little/too-late for someone with her type & degree of disturbance.
I was okay with the ending & am glad they didn't decide to lighten things up & make it more commercially viable by going for a "happy ending" & having Nancy live happily ever after w/ Louis. That would be too Hollywood. In real life, some people simply can't overcome the pain of such prolonged and heinous abuse & end up choosing death over life as the ultimate release from unbearable pain...
