The unpredictable shifts and changes within evolving relationships are given plenty of screen time in LOVE IS NOT ENOUGH. The film, shot in Detroit, my old stomping ground, is PG-rated romantic-themed drama that is definitely aimed at female audiences.
This has a casual, easy pace, features no cussing, next to no nudity or sex, and has solid production values. Couples may find the sexual politics an interesting case for discussion, although potential lady viewers will be happy to know that all ends with a pro-relationship viewpoint where the woman is mostly right.
Personally, the film not only convinced me that love is not enough, but it also convinced me that the compromises the male characters made in this movie (for the women) would, ultimately just make them resentful –– a lot of questionable "simping"/White Knighting going on here.
There is definitely an audience for these more PC-sensitive dramas, and this should meet your criteria if you err towards such subject matter.
