Love Letters - Men We Have Loved(2003)

The husband leaves home, leaving behind his wife and child and his job as a middle school teacher. He leaves all this to live with a former girlfriend so that he can nurse her as she battles with terminal illness. He has decided to nurse her until the end. This sudden take-charge approach from a man she thought of as indecisive causes the wife to look at her husband in a completely different way. To top it off, the husband asks her to drop in on the ex-girlfriend from time to time to keep her company. Despite herself, she agrees to her husband's request. She thought that cursing her husband and celebrating the ex-girlfriend's suffering would make her feel better but instead she finds herself even more attracted to him. She even finds herself growing closer to the ex-girlfriend, creating a curious bond between the two women. In the midst of all this, the relationship between the husband and wife continues to change.
