It all comes down to this! Married at First Sight's season 3 finale on Tuesday, March 1, will reveal the fate of its two remaining couples, and there are plenty of jitters before everyone's final decisions get revealed, as seen in Us Weekly's exclusive sneak peek.

In the FYI series' clip, Neil is less certain than Sam about whether they should stay together, given that he still feels hurt by their relationship's previous turbulence.

"Sam is understandably feeling more in knots than I am because she doesn't know how I feel," Neil admits to the camera. "At the moment, I'm on the fence."

As the couple talks in bed about where they stand, Sam gets emotional when they both acknowledge how much progress they've made as a couple.

"I'm still 100 percent committed to this marriage — I want to make this work, and I hope Neil figures out what he needs to make this huge decision that could impact the rest of our lives," she says to the camera.

Last week's first part of the finale was a tough one for David and Ashley, as she decided to end their marriage despite her husband still hoping to fix things between them.

Watch the video above to see why Neil refers to one of Sam's questions as "ridiculous."

The second part of Married at First Sight's season 3 finale airs on FYI on Tuesday, March 1, at 9 p.m. EST. The series is produced by Kinetic Content.
