“Married at First Sight” fans won’t be able to watch strangers getting married until Season 3, but the new series “Seven Year Switch” might still fill the “MAFS” void. After all, they have plenty in common. FYI’s new docu-series follows what the network calls “experimental marriages” and ends with a final decision that involves either staying married or getting divorced.

It isn’t exactly “Married at First Sight,” of course. In fact, it’s kind of the opposite. The couples in the experiment know each other very well. Four couples have all been married for seven years, and they’re having problems. They decide to get a new partner for two weeks. The experiment is designed to “help determine if different traits and characteristics in a mate could make their marriage stronger,” according to FYI’s press release.

Their new partnership will help them evaluate their marriage. After the two weeks are up, the couples will have to decide if they want to stay married or get divorced. The couples that stay together will get to renew their vows.

The first trailer for “Seven Year Switch” shows that the couples are hoping their marriages can handle the experiment. None of the participants really want to leave their spouses. They’re hoping that the reality show helps them stay together in the long run. 

“There’s a lot at stake here. Houston and I are very invested in our relationship,” one wife says. “So for it to not work out would be a tragedy.”

“I think absence can make your heart just long for each other even more,” another wife says before she and her husband engage in a tearful goodbye.

“Seven Year Switch” is produced by Kinetic Content, who also produces “Married at First Sight.” Hopefully, this experiment will go better than the last season of “Married at First Sight.” At the end of the initial experiment, only one couple decided to get a divorce. However, in the Season 2 reunion special the couples that stayed together revealed that they also were getting divorces.

“Seven Year Switch” premieres Tuesday, July 7, at 9 p.m. EDT on FYI. Will you be tuning in? Sound off in the comments section below!
