“90 Day Fiancé” Season 12 participant Catie admitted to multiple instances of infidelity with other individuals shortly after marrying her husband, Josh. These revelations came to light during the first part of the season’s tell-all special, which aired Sunday on TLC.

During the tell-all, Catie experienced emotional breakdowns when confronted about her behavior. She acknowledged infidelity on New Year's Eve, stating, “On New Year’s Eve, I was bad,” and admitted to kissing four other people. Her fellow cast members reacted with silence, indicating disapproval.

Josh expressed disappointment in Catie for “crossing boundaries.” When questioned by host Shaun Robinson if her behavior was problematic, Catie became tearful, saying, “Everyone thinks I’m a bad person. I don’t like this. I’ve been trying to get better.”

The show replayed footage of Catie attempting to kiss friends in front of Josh, to which she responded, “I’m stress laughing.”

Further details emerged when friends Ryan and Danica were brought in. Danica recounted a New Year's Eve party hosted by Catie and Josh, where Catie allegedly made out with her “crush” from a running club twice, once in Josh's presence. Danica also stated that Catie, 26, later kissed two more people that night, including a man in his 50s named Robert. Josh, 30, intervened when he saw Catie entering a bathroom with the first individual she kissed, asking him to leave. Catie admitted the situation might have escalated beyond kissing if Josh had not intervened.

Catie then had an outburst, telling Josh, “I can do whatever I want. I don’t have to listen to you!” She added, “I just want to be young and just live my life.” When asked by castmates if she wanted to be married, she began to cry and exclaimed, “I don’t know!”

Catie declared, “I don’t enjoy being together, sorry. I think I do better on my own.” She then exited the tell-all. Backstage, she told a producer, “I don’t care if I make out with people, it’s fine. I don’t want to talk to any of them ever again.”

“90 Day Fiancé” airs Sundays at 8 p.m. ET/PT on TLC.
