Double Lover (2017) on Netflix

Plot summary

Chloé is 25 and used to work as a model. She suffers from severe abdominal pain, and a gynecologist tells her the trouble is psychosomatic and sends her to a psychiatrist. She begins sessions with Dr Paul Meyer, and her condition improves under his care. Because he has grown attached to her, he brings the treatment to an end, and the two become involved. Months later they move in together. While they unpack, Chloé learns that the surname Paul goes by is not the one he was born with, and that he has said nothing about his family. She works as a museum attendant.
