Will she forgive him? Fernanda Flores can’t fight back the tears after finding a thong in Jonathan Rivera‘s place. The 90 Day Fiancé star broke down while chatting with one of his friends about the ordeal in a new sneak peek, revealing the incident has really given her trust issues.

Fernanda moved into Jonathan’s house during last week’s premiere and was shocked to find another woman’s underwear. “It’s hard [to] talk with Jonathan’s friends about our problem. I feel, of course, more comfortable talking with my friends but I don’t have [that] option,” the 19-year-old admitted in Us Weekly’s sneak peek of the upcoming Nov. 4 episode. “If I told my friends and my family, they will be disappointed in Jonathan.” Jonathan’s friend tries to reason with Fernanda, explaining that maybe he just moved drawers with old clothes and didn’t think twice about it.

“It was terrible,” Fernanda said, while visibly upset. “When I came here, I’m so excited and it made me feel stupid… I want to believe in him, but you think the worst.” Jonathan’s friend was clearly trying to put herself in Fernanda’s shoes, revealing that if she left everything behind to marry someone only to discover a pair of underwear, she’d also be upset. “This is typical Jonathan,” his friend said in the confessional. “No telling how long that’s been in there. He hasn’t thought about it. He’s just a boy and he’s dumb.”

Jonathan and Fernanda have the biggest age gap out of all the couples on Season 6 of TLC’s hit reality TV series — 12 years. The reality star, 32, proposed to Fernanda after three months of dating, and he said he would try to visit her as often as he could in Mexico, but that wasn’t always easy considering he works as a realtor. The couple applied for the K-1 visa and fans are eager to see how they handle the ups and downs of their relationship. Hopefully things work out for the best!
