Kody Brown may have four wives, but the patriarch of the beloved plural family admitted that even he has fears when it comes to marriage. During the Season 6 finale of “Sister Wives,” the husband of Meri, Janelle, Christine and Robyn divulged what those worries were after sitting down with Caleb to discuss the possibility of him marrying his daughter Maddie.

“Being in love doesn’t always do it,” Kody said in a confessional after having a heart-to-heart with the man pinning to marry his daughter. “Sometimes you can feel like the person you loved yesterday is your enemy.”

Kody’s remark came at an interesting time during the TLC series. Moments after he expressed his concerns with longtime relationships, Meri, Kody’s first wife, revealed to her family that she had something she wanted to share with them -- something that she felt could destroy their family.

The secret she was referring to was the emotional, online affair she had with a woman who was pretending to be a man.

“I got into this place where I was talking to different people on social media I got into this situation [where I was] talking to one person who really made me trust him,” Meri explained during the Season 6 finale, revealing that due to her feelings of loneliness, she latched on to the kind and compassionate stranger for comfort.

But soon Meri’s friendship with her online suitor developed into something a little more serious. “He was really starting to make me feel love for who he was portraying himself to be,” she admitted. “It was really confusing because I was really caring for him, too. It was probably one of the most confusing situations I’ve ever been in because I’m sitting here married and I’m feeling these other emotions, directed toward somebody else.”

However, Meri didn’t act on those feelings, which is when her relationship with the Internet stranger became abusive. Following the verbal attacks, Kody’s wife did some investigating and learned she had been catfished by a woman taking on the identity of a man.

“It was a woman who had been watching me online and I feel like I have been targeted and I feel like my family has been targeted,” Meri said, explaining that she pushed her family away after learning the truth to protect them.

As Meri unloaded her struggles to her husband and fellow sister wives, Kody remained quiet. The patriarch of the polygamist clan divulged during his confessional that the reason he stayed tight-lipped was because he was confused by his wife’s admission. (Meri revealed she was contemplating packing up her belongings and leaving.)

“Meri is saying she’s really struggling [and] feels like she lost her identity. And it’s weird, some of the words she’s saying sounds like she’s leaving or something. I don’t know what to make of this,” Kody said. “I’m gathering from this [that] that she doesn’t want to be married to me anymore but that she still wants to be in this family. I’m afraid to ask her -- I’m afraid she’s she going to get in my face and say, ‘This is you.’”

Fans will find out where Kody and Meri Brown stand when TLC airs a two-hour “Sister Wives” special on Sunday, Nov. 22, at 8 p.m. EST.
