"'Decision Day' is only one week away. What pros and cons are you weighing about your marriage at the end of this experiment?" host Jamie Otis asked Katie on the April 8 broadcast of Married at First Sight: Unfiltered.
"Some pros are that we seem to resolve fights pretty quickly. Once we cool off, we're able to sit down and talk about how we feel and see each other's point of view and get over fights pretty quickly," Katie explained.
"But the con is that they happen a lot. The fights are happening, it seems, more and more -- the more we get to know each other."
"So that makes me have some concerns," Katie admitted.
Katie, who is admittedly a little jealous and insecure sometimes in her relationships, has complained on Married at First Sight's tenth season multiple times about how Derek supposedly failed to make her feel special and never initiated physical intimacy in the bedroom.
Katie has accused Derek of flirting with the other wives on the show, and she feared throughout the entire process Derek might never fall in love with her.
"I think Katie could be the person that I want to spend the rest of my life with, the person I want to madly love and never look back," Derek said in a confessional in the latest Married at First Sight episode.
"So, I need to figure out how to reassure Katie that she should say, 'Yes,' [on Decision Day]. I want her to say, 'Yes.'"

Katie, however, wasn't sure Derek was "the" guy for her since they aren't very compatible and had developed more of a friendship than a romance. She seemed torn on whether to stay married or ask for a divorce come "Decision Day."
"I don't feel special at all... There is a giant emotional disconnect. As soon as I think I'm closing the gap, it shoots way open again," Katie explained to her father Dante.
Katie didn't think Derek knew how to express himself, and she called him "a boy" instead of a man.
Katie had been hoping for an older, more mature man waiting for her at the altar, but she said she got a baby-faced boy with a baby personality to match.
