Teary Meri Brown Reveals Horrible Situation In 'Sister Wives' Preview

Meri Brown's catfish scandal is likely to come to light on Sunday's edition of Sister Wives, in which Kody Brown's first spouse opens up about a very bad situation she's brought into the large household.

"They have no idea how bad it is -- they don't know what I brought into the family," Meri is heard saying in a preview for the TLC hit. "It's no surprise I've been struggling with … stuff."

Meri herself came clean about the touchy situation speaking with People last month, saying that "during an emotional and vulnerable time earlier this year, I began speaking with someone online who turned out to be not who they said they were.

"I never met this person and I regret being drawn into this situation, but I hope because of it I can help others who find themselves in similar circumstances."

Meri, 44, said that the situation made for "a very difficult time" that caused her tons of anxiety, but the family camera around to support her though the stormy period. The string of incidents came after Meri and Kody's 2014 divorce, after 24 years of marriage, to open Kody up to allow her sister wife Robyn and adopt her three kids.

As RadarOnline.com previously reported, sources told In Touch Weekly that Meri was linked to a Chicago man named "Sam Cooper" in an online romance in which she left more than 10 emotional voicemails, calling for his love and acceptance.

Sources told the magazine that her sister wife "Robyn absolutely knew from the beginning that Meri was being catfished," and "sat back and just watched as the whole scam unraveled," but Robyn's pal Kendra Pollard-Parra insisted to RadarOnline.com that "Robyn has nothing to do with it."
