Fans of 90 Day Fiancé are freaking out after last week’s episode’s cliffhanger and are wondering what really made Natalie not trust Mike. Did he cheat on her? The couple has been on rocky terms since Mike’s trip to Kyiv and fans are wondering where the couple stands after Natalie threw her engagement ring in his suitcase as he left back to America.

Mike and Natalie are one of the newer couples to the 90 Day Fiancé franchise and have already given viewers some embarrassing moments thanks to their differences in religion, culture, family values and of course a language barrier. The two originally met through Mike’s friend, Matt. Mike’s close friend is married to a Ukrainian woman and asked Mike to be the godfather to their newborn. The Washington state native then met the godmother, who turned out to be Natalie and was influenced - thanks to his friend for showing him pictures of the Kyiv native - to ask her out on a date. After many arguments on his recent trip to Ukraine, it came to a head on the last day together as the two had a heated argument after Natalie revealed to cameras that it would be a lie for her to say she’s in love with Mike.

On the season finale of 90 Day Fiancé which aired Sunday, fans watched as Mike and Natalie grew even farther apart after not speaking for a week after Mike returned home. During the episode, Mike decided to try and call his fiancé to figure out how they could move on. During his last visit to Kyiv, the two argue constantly and seemed to find it hard to search out a natural ground. One of their biggest arguments was over religion as Natalie was devout in her faith while Mike believed aliens were out there watching them.

Though most fans believe that Natalie often acts quite childish when it comes to interacting with her future husband, they oftentimes take Mike’s side. Natalie would often shut down and retreat into her mother’s arms or her oversized sweaters and wait for Mike to run to her with an apology. However, Mike seemed to be tiring of false apologies and it all came to a blow when he was at the airport ready to board his flight. Natalie not only threw the engagement ring back in his face but then refused to kiss him goodbye. The Kyiv native’s mixed signals were not only confusing to Mike but also came across as a bizarre characteristic to many fans.

During the couple’s final Facetime of the season, Mike told Natalie that he always loved her but as of now did not know where his heart stood. While Mike tried to ask Natalie important questions about the future, however, she would refuse to answer, instead, she would repeat his exact question back to him. Natalie ultimately replied that she had given Mike back her ring due to something that they both were aware of, saying, “I had my reasons. And you know.” The production crew was not prepared for such an answer as Natalie continued her rant, “Go to America for a man I cannot even trust? I will not do this.” Fans watched as producers quickly asked Mike what his fiancé meant, only to be met with complete silence when they probed further about their trust issues and if something had happened off-camera. The Washington native eventually replied to their question saying, “I don’t know what’s honestly going through her head.” The reality star then exited the confessional room with teary eyes.

The whole interaction left fans confused and bewildered leading many to think that Mike cheated on Natalie. The implication of Natale’s words sheds a terrible light on Mike especially since he did not respond to the production crew. But some believe that Natalie is the one at fault for their piss poor relationship and possibly she was the one who cheated. Fans will have to wait and see what happens during the explosive tell-all episode, which teased that Mike and Natalie have a very intense video call in which they speak about the secret that Natalie is withholding. Hopefully, the tell-all episode will give fans the answers they so desperately crave.
