The social experiment will officially come to an end in the upcoming "Married at First Sight" season 3 finale. That being said, the couples will have to decide whether or not they want to continue their relationships beyond the show.

FYI released a teaser for the affair and it shows how tense everyone is on "decision day." However, it's different for Vanessa, who does not look worried at all. As she attempts to break it to a nervous Tres, she is even smiling. Many "Married at First Sight" season 3 followers root for this couple to stay married.

Their journey was the smoothest, at least compared to the other two couples. They are the only ones who consummated their marriage and they have been doing their best to make each other happy. 

However, in the previous week of "Married at First Sight" season 3, Vanessa noticed Tres's lack of commitment. They have been thinking about what to do after the show but Tres appears to not be on board with Vanessa just yet.

As for Neil and Sam, the "Married at First Sight" season 3 sneak peek saw how stressing it was for the two. Sam even walked out of the room as Neil breathed heavily nonstop, waiting for the verdict. This couple has made quite a big progress towards the end of the show.

In the first weeks, the two basically can't even communicate. After horrible living arrangements with Sam's roommate, they eventually came to terms about getting a place to stay where they'll both be at home.

Ever since, the two have grown closer than ever. Sam even admitted that she was starting to like Neil. She even missed her husband when he went out of town for one weekend. Neil is just proud they are on the right track.

It could be that these two are thinking of giving their marriage one more shot after "Married at First Sight" season 3. There are also rumors that the two were seen in public together and that they are still seeing each other so there might actually be a chance of them continuing the spark.

Lastly, there's David and Ashley, who, from day one, failed to get along. It does not look like they've gotten to know each other well in the one and a half months they were together. The last episode, however, was a big 360 for the two seeing how much fun they had hanging out and how many sweet moments they shared.

While it looks like they are willing to give their marriage another shot, it won't be a shock seeing them call it quits. What will become of the couples? Watch the first part of the "Married at First Sight" season 3 finale on Feb. 23 on FYI.
