Sabrina Spellman, the titular character of the popular television series Sabrina the Teenage Witch, almost marries Harvey Kinkle in the original series. Their relationship was a major plot point throughout the show, and their eventual separation was a significant turning point for Sabrina's character arc.
Their near-marriage occurred in the season 4 episode "The Marriage Game," where Sabrina and Harvey, facing a magical curse that forced them to marry if they spent the night together, decided to take a leap of faith and tie the knot. Ultimately, the curse was broken, and Sabrina realized that she wasn't ready to commit to marriage, especially not with Harvey.
However, their relationship continued throughout the series, and they eventually broke up after Sabrina's decision to embrace her magical heritage and attend the Academy of Unseen Arts.
While Sabrina almost married Harvey in the original series, the Sabrina the Teenage Witch reboot, titled Chilling Adventures of Sabrina, has a different storyline altogether. This version of Sabrina does not marry Harvey, and her romantic relationships are explored differently.
Note: This answer focuses on the original Sabrina the Teenage Witch series, as the question does not specify which show.
