In this ValentinesDayEpisode, Bart reunites with Mary (Cletus the Slack-Jawed Yokel's daughter who moved to New York and writes for ''Saturday Night Live''), but their relationship drifts apart and Bart must win back Mary or lose her forever.
!!"Love is a Many-Splintered Thing" contains examples of:

* DisproportionateRetribution: Marge not only kicks Homer out, but ''Bart'' as well, all because of a frustrated response about women never saying what they mean (shortly after Mary broke up with him over the phone).
* DownerEnding: [[spoiler:While Homer wins Marge back after going through leaps and bounds (once again), Mary dumps Bart and is now dating the son of a Brazilian producer.]]
** [[spoiler: HopeSpot: The episode ends with her relationship status updating from 'married' to 'single.']]
