Can't get past...
I keep dwelling on Jessica's situation. When she becomes resigned to her fate (for the time being), she is basically not fighting Simon anymore, presumably not fighting him even in the bedroom. Thank god that's implied and not shown. That's serious psychological horror in my book. That aspect of the movie is what elevates it above most other Lifetime movies.
On another point, for all of Simon's traditionalism about gender roles, he's essentially having sex (to him; what the women are experiencing is rape) outside of matrimony.
