Sun Jul 25, 2021 at 10:45pm ET Season 12 of Married at First Sight proved to be the franchise’s most dramatic season yet. Pic credit: Lifetime Season 12 of Married at First Sight ended with three couples choosing to stay together on Decision Day, but that’s not exactly how it ended. The experiment based in Atlanta proved to be the franchise’s most drama-filled yet. From a pregnant ex-fiancee to very conflicting personalities, the couples had their fair share of very heated arguments this season. Despite three out of five matches choosing to stay together on the season’s finale, since the show wrapped, a lot has changed.
