Jonathan, a 32-year-old from Lumberton, NC, met Fernanda, a 19-year-old from Mexico, at a club during his vacation to 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 proposed marriage to Fernanda after dating for only three months.
Fernanda's visa was subsequently approved, and the 90 Day Fiance 'sepisodes have shown Fernanda getting settled into Jonathan's place after arriving in the United States.
So are Fernanda and Jonathan still together? Did they end up getting married during Fernanda's 90-day stay in America?
According to their social media postings, Fernanda and Jonathan are not only still a couple, but they are husband and wife!
Jonathan can be seen wearing what appears to be a wedding ring in some his recent photos on Instagram, and his mother also posted about the couple's May 5 courthouse wedding on Facebook earlier this year.
On October 1, a Reddit user who claims to be a former classmate of Jonathan's shared screenshots of a post Jonathan's mother had written on Facebook in May. She called her son's nuptials a "fairy tale."
"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," Jonathan's mother allegedly wrote in the posting, which also included a collection of photos of the courthouse ceremony.

"May God bless you two, guide you throughout your marriage with love, patience, compassion, and honor for one another. Can't wait for next year for the wedding fiesta celebration in Mexico! Congratulations!! I love you both!"
Fernanda was shown wearing a high-collared white dress with bell sleeves in the photos, while Jonathan wore a blue suit with a white dress shirt and pale pink tie.
Recent social media photos would also appear to confirm Jonathan and Fernanda are married because Fernanda is still living in the United States and her K-1 visa would have expired by the end of May and required her to return to Mexico if the pair had not married.
Fernanda apparently arrived in the United States on her K-1 visa in late February.
"Happy Valentine's Day to this beautiful soul! The one who gets me out of bed in the morning, the one keeps me grounded and always supports my dreams. She does the little things and I am constantly reminded how lucky I am. To my best friend and future wife, I love you baby!! U.S. bound in a couple days!! @heyfer8," Jonathan captioned a February 16 photo.
And then on February 24, Jonathan shared a picture with Fernanda at a gala in Lumberton, North Carolina.
Moving on to April 10, the pair attended opening day for the Chicago Cubs baseball team. And on April 24, Jonathan posted a photo in which he was still referring to Fernanda as his "fiance."
On August 24, Jonathan also shared a picture of what he said was the previous day's sunset with Fernanda in the photo.
Social-media evidence of the couple's relationship continued into September, when Jonathan posted a photo showing the couple had traveled to Chicago to escape Hurricane Florence, which caused severe damage in the Carolinas.
He captioned the image, "With my ride or die Chic, doing ride or die sh-t in Chicago. #chicago #rideordie #pic #hungry #escapingflorence #misshome #readytowork #makethebestofit #prayingforfriends."
Later that month, Fernanda posted a photo from the couple's trip to Los Angeles, CA. She wrote alongside the photo, "Something tells me I'm going to love him forever."
Not only did Jonathan also bring Fernanda to his brother's wedding, but he shared a sweet picture on September 25 with the following caption about Fernanda: "Distance meant nothing because you meant everything. #herebymyside #pic #strongertogether #bosslady #powerfulwoman #fierce #couplegoals."
After 90 Day Fiance's sixth season debuted on October 21, Fernanda posted a couple of photos featuring the pair dressed up as glamorous skeletons for Halloween on October 31.
And as recently as November 8, Fernanda shared a selfie of the couple holding hands in a car.
