In "The Office," Michael marries Holly Flax and moves to Colorado with her.
Holly is introduced as Toby’s replacement in the Scranton branch’s human-resources department. Played by Amy Ryan, she shares Michael’s unusual humor, optimism, and emotional awkwardness. Their relationship becomes one of the show’s central romances, even after corporate decisions repeatedly separate them.
Michael proposes to Holly during the Season 7 episode "Garage Sale." He then announces that he is leaving Dunder Mifflin to join her in Colorado, where she needs to help care for her parents. The series later establishes that Michael and Holly marry and build a family together, although their wedding itself is not shown in a regular episode.
Holly is sometimes confused with Michael’s earlier partners, including Jan Levinson, Carol Stills, and Donna Newton. None of those relationships leads to his lasting marriage or move away from Scranton. Holly’s full name is Hollis Partridge Flax, and Amy Ryan played her throughout the American series.
