Giannina and Damien are the first to take a walk down that wedding aisle and their ceremony was definitely memorable! Though Giannina tearfully proclaimed her love for her fianceé, he didn't feel like they were ready to take that leap and told the younger woman he couldn't marry her. Cue Giannina running out in tears before she returned to angrily confront Damien about his decision.
Damien explained that he hasn't felt like Giannina was "all-in" for their relationship until that very day and all of her actions beforehand told him she wasn't ready for marriage. Though he expressed hope that their relationship could recover from the failed wedding, it's highly unlikely that Giannina will be able to move on from being dumped at the altar.
