One of the many discussed topics on the "Real Housewives of Salt Lake City" has been the end of Lisa Barlow and Meredith Marks' friendship.

Following the Wednesday Season 3 episode, Marks made an appearance on "Watch What Happens Live with Andy Cohen," where she explained why she was unwilling to repair her friendship with Barlow.

Fans were surprised during the Season 3 premiere when the pair were still feuding even though Marks forgave fellow cast member Jen Shah after claiming Shah traumatized her family.

Barlow apologized after she was heard on a "hot microphone" insulting Marks and her family during "RHOSLC" Season 2. Nonetheless, Marks said she is struggling to move on from the incident, saying Barlow lacked accountability.

"She refused to explain the behavior, like the underlying causes. She refused to give me any reassurance that it wouldn't really happen again, other than saying, 'I won't do it again,'" Marks told a fan on "WWHL."

The jewelry designer said she felt confident about keeping her damaged relationship with Barlow the way it was because she suspects that Barlow has spoken negatively about her on more than one occasion.

"I was very open. There was a lot more that unfolded after, and it was not the first time..." Marks explained.

"I'm done with it. I'm disengaging from Lisa Barlow at this point, because she's continued to make excuses for her behavior. An apology that has excuses attached to it is not an apology."

However, Barlow appeared to slam Mark's comment about the end of their friendship. "This is all lies. @MeredithMarks0 you're lying," Barlow tweeted during the Wednesday episode of "WWHL."

Barlow continued to tweet throughout the night and told a fan that she would remain at odds with Marks because "you can't move forward when someone is committed to hating you."

"The Real Housewives of Salt Lake City" Season 3 airs Wednesday at 9 p.m. ET on Bravo.
