The day has come for the "Married at First Sight" season 4 couples to choose if they want to stay as husband and wife or go their separate ways. Their second honeymoon was crucial for this decision.

For Tom and Lillian, it was to solidify their decision to stay married. However, the trip appears to have proven otherwise after the two learned they have completely irreconcilable ways of life.

Tom lives in a bus that he loves very much. It is what they used to visit places during their second honeymoon in the previous episode of "Married at First Sight" season 4.

However, his wife was not too thrilled about it at all, from how long it takes to move it, to the very idea of starting a family in it. Clearly, this will have a huge effect on their decision come "Married at First Sight" season 4 episode 14.

"Before I met Lilly, the bus was a huge part of my life and I feel like it is something I'm not ready to give up," Tom admitted to the camera.

"Tom and I have completely different lifestyles, and I'm trying to figure out which is more important for Tom—the marriage or the lifestyle," Lillian said.

This started to sour the marriage a bit, and fans will see that manifest in "Married at First Sight" season 4 episode 14 with Tom "pulling away" from Lillian as he starts to think that his wife may not be "the exact person I was hoping for."

As for Nick and Sonia, their second honeymoon did not go so well either. They did not get intimate at all, but they did sleep in the same bed. It looked like the trip did not help convince Sonia to move back in.

Nick said that with that situation, his marriage is already over prior to "Married at First Sight" season 4 episode 14. That being said, it looks like the two remaining couples are on the brink of divorce.

"Married at First Sight" season 4 episode 14, "Till Death Do Us Part," airs on Tuesday, Oct. 25, at 8:30 p.m. ET on FYI.
