Making good on the trailer's promise to deliver drama, "The Culpo Sisters" opened with the shock reveal that Mikey Bortone had been unfaithful to Aurora Culpo. This infidelity ultimately led to the couple's divorce. In the episode, Aurora detailed what happened, telling her sisters that an anonymous person had DM'ed her with news that Bortone had cheated (via E! News). When she confronted her husband, Bortone admitted to an affair, and to cheating on Aurora more than once.

However, things weren't as black and white as viewers might assume. That's because Aurora had given her husband a hall pass earlier in their relationship. "Because I was so confident that nothing could ever come between what we had ... he was allowed to have one a year, like hook up with a random person," Aurora said. While Olivia and Sophia Culpo were shocked, Aurora went on to say that things had since changed, and Bortone's hall pass days were over. "Now that I've experienced it, I don't like it and I said, 'Is that something that you are going to be OK with?' and [Bortone] said he was going to think about it and let me know. He's like, 'Well, you changed,'" Aurora added (via ET). "And I'm not happy that he's not changing."

Change can be a positive in many relationships, but as Aurora sought new growth, it put strain on her marriage.
