Pavelka's choice of Girardi had been widely panned.
On the season finale, Pavelka professed to being in love with both women, but expressed a stronger physical attraction for Girardi than for Molzahn, who works in college admissions.
Girardi, a marketing representative and former Hooters restaurant waitress, had stirred up controversy among her fellow contestants and the show's fans throughout the season.
Many of the contestants had described Girardi as immature and a source of drama in the house, but she defended herself by saying she was simply being honest, and being herself.
When Pavelka's family members met the two finalists, they preferred Molzahn.
Pavelka's mother Sallie called the two "the perfect couple," but said the other contestants' reaction to Girardi was "a red flag."
Sallie Pavelka later said she no longer had concerns about Girardi and that she was convinced that Girardi loved her son.
