An eye-opening road trip to meet with a different polygamist family could have some severe consequences for the Brown family on Sister Wives.

Tensions Increase During Brown Family Road Trip?

Meri Brown, Kody's first wife, revealed in the latest episode after meeting the Richard family, that she could understand how fellow "first wife" Rebecca Richard felt about initially becoming part of a polygamist family-and admitted that some days she still feels a sense of betrayal to the original marriage she had with Kody.

The feelings were revealed after Rebecca admitted to her own agony when husband Nathanael chose to also marry Christina and start a family with her as well.

"I felt like he wanted to cheat on me...I wondered, 'what is it that I'm not doing that's making you feel like you need this other person in your life?'" she said during the July 13 episode.

Though the Richard family came into a polygamist marriage because they felt they were "called" to do it, whereas the Browns grew up in a fundamentalist offshoot of the Mormon church, Meri was able to sympathize with Rebecca, and revealed that there are times she still doesn't know if she made the right decision.

"I'm happy on the good days and when Kody shows love and affection, but on a bad day, I question my importance to the family and if Kody still cares about me," she admitted.

It isn't the first indication Meri has given that she could be unhappy with the arrangement either-the current season began with her revealing to Kody that she wanted to go back to college and begin a career of her own-opening up for the first time about how she has previously lost opportunities in the field she loves due to her polygamist marriage.

"When we were living in Utah, I had started going to college, and I was really enjoying it. It was very fulfilling to me," she said at the time. "I ended up working at a residential treatment center for at-risk youth and I love it. Loved love loved it. I ended up losing that job because of my lifestyle, because of going public, because of an investigation. So I never went back to college after that."

Sister Wives airs Sundays at 9 p.m. on TLC.
