Jonathan Rivera and Fernanda Flores' relationship began when they met at a club while Jonathan was on vacation in Mexico with his best friend. The real estate broker fell hard and fast for Fernanda, saying the world stopped when he first saw her.

Despite their age difference, Jonathan, 32, proposed marriage to Fernanda, 19, after dating for only three months. Fernanda's K-1 visa was subsequently approved, and 90 Day Fiance's sixth season showed Fernanda and Jonathan planning their wedding in the United States.

Fernanda arrived in America on her K-1 visa in late February 2018 and the couple got married in a courthouse wedding in May that Jonathan's mother revealed in a Facebook posting.

"A couple of weeks ago, my son, Jon (Jonathan) and his beautiful fiance Fernanda decided to get hitched -- pronto! On May 5, they became husband & wife," she wrote in the posting, which also included a collection of photos of the courthouse ceremony.

Fernanda and Jonathan were pretty open that they were still together in their social media postings throughout Fall 2018, and Fernanda had even confirmed their marriage status.

In early December, Fernanda had even posted a slideshow of wedding photos from a Christmas-themed photo shoot the couple had participated in together.

However, the couple suddenly split shortly before Christmas.

After being asked by Instagram followers why he and Fernanda were not celebrating New Year's Eve 2019 together, Jonathan confirmed the couple had separated and Fernanda was currently staying with friends and family in Houston.

Fernanda then told her followers she was aware of her husband's postings but didn't want to comment on them.

"I don't want to talk anything about Jonathan again. Please don't ask questions about him," Fernanda said live Instagram chat with her followers on New Year's Day.

"He's talking a lot; he can say whatever he wants. I'm not going to talk about it until I'm ready. And today and right now is not the moment. So, let's enjoy the rest of this day."

However, Fernanda finally broke her silence on January 19.

"He is the one with no intentions of fix[ing] our marriage," she replied in an Instagram comment to one of her followers.

Later that night, she also posted a tweet in which she said she was "done" trying to convince Jonathan to give their marriage another chance.

"Estoy cansada de quedarme callada, sumisa, paci­fica, estupida, esperanzada a reparar lo irreparable. Is he done? Guess what I'm done too," the 90 Day Fiance star wrote on Twitter.

Translated to English, the Spanish portion of her tweet reads, "I'm tired of being quiet, submissive, pacifying, stupid, hopeful to repair the irreparable."

In March 2019, Jonathan posted an Instagram message boasting that he had canceled the I-184 affidavit of support form he had previously filed to support Fernanda's U.S. residency application.

In April 2019, TLC released Season 3 of 90 Day Fiance: What Now?, its online digital series that is available for streaming on tlc.com and the network's TLC GO app.  The 21-episode season included three episodes focused on Jonathan and Fernanda.

The 90 Day Fiance: What Now? episodes revealed shocking new details about the events that led up to Jonathan and Fernanda's break-up and confirmed Jonathan has filed for divorce.

The major point of contention in the former couple's marriage was living in Lumberton, NC, where Jonathan works as a real estate agent, according to 90 Day Fiance: What Now?.

Fernanda, a self-declared "big city girl," felt lonely, bored and "trapped" in her home and desired a move to Chicago so she could pursue modeling and take acting classes.

Fernanda insisted Jonathan had promised her they would move before she decided to leave her home in Mexico to be with him.

In May 2019, Jonathan went Instagram official with his new girlfriend Janelle Miller.

Then in June, Fernanda finally revealed her side of her break-up with Jonathan and made several shocking allegations against him -- including claims that he was mentally, verbally and physically abusive to her during their marriage, and that he also cheated on her.

Fernanda made her allegations in a lengthy 44-minute video titled "My Truth" that she posted to YouTube six months after the sixth-season 90 Day Fiance couple suddenly split before Christmas.

"I'm doing this video to clarify some things about my split... after six months, I'm finally ready," Fernanda explained in the beginning of the video.

"I was concentrating on myself and now I'm in such a better place to let you know the truth. I didn't want to sell my part of the story to any network because I'm not looking for attention [nor] money."

According to Fernanda, the couple's problems traced back to an agreement they made before Fernanda she even agreed to come to America: that they would only live in Lumberton, NC for a year and then move to Chicago, where Jonathan's family lives and where the sister and parents of her father, an American citizen who currently lives in Houston, also reside.

Fernanda also claimed it was Jonathan's idea that they appear on 90 Day Fiance, and that she was unsure whether it would be a wise decision to have cameras chronicling their relationship but Jonathan convinced her it would be good for them -- and especially his real-estate agent business.

In March 2020, Fernanda took to Instagram and announced she and Jonathan were officially divorced.

"Officially single!" she captioned photos of herself proudly sitting outside a Chicago courthouse with a big smile on her face and one fist victoriously raised in the air.

Three months later, Jonathan announced his engagement to Janelle after about a year of dating.

"Easiest decision I've ever made," he captioned an Instagram slideshow of photos with Janelle in which she was showing off a large pear-shaped engagement ring.
