Married at First Sight star Luke Cuccurullo admits his wife Kate Sisk wasn't the only one in their relationship who was a tad reluctant to move in together so quickly. During Tuesday night's episode of Married at First Sight: Unfiltered, Luke and his Season 8 co-stars Keith Dewar and AJ Vollmoeller discussed with host Jamie Otis how they dealt with the extreme change of living with someone only two weeks after marrying a complete stranger.

(PHOTOS) Although Kate appeared hesitant and anxious about moving in with Luke on Married at First Sight, he acknowledged he was very nervous about the big step as well. "We were both hesitant," Luke confirmed on Unfiltered. "Neither one of us had ever lived with somebody before, so this was brand new for both of us. But once we found our routines, it [began to feel] more normal." The situation was also a huge lifestyle change for AJ, who lived alone for quite some time prior to meeting his wife Stephanie Sersen at the altar. "I've never lived with a significant other, never been engaged. I'm pretty traditional in that aspect," AJ revealed. "I've always wanted to do it in the right order. I didn't want to move in with somebody until we were at least engaged, if not married." Jamie then poked fun at AJ for tying the knot with a stranger given an arranged marriage is far from traditional nowadays, but AJ validated his point by quipping, "And then I moved in with her!" As for Keith, his life drastically changed by leaving his grandmother's house and moving in with Kristine Killingsworth. RELATED LINK: '90 DAY FIANCE' COUPLES NOW: WHO'S STILL TOGETHER?
