Woman says she helped her roommate move in — then months later she walked in on her sleeping with her father and realized the entire friendship may have been built on a lie

A woman on Reddit said a hiring email at work dragged her back into one of the most humiliating betrayals of her life.

She wrote that her manager sent the team a shortlist of job candidates and asked whether anyone had prior experience with any of them. One name stopped her cold. It was a woman she called “Cersei,” someone she used to be friends with and who had briefly been her roommate. The problem was not that they had a falling-out over chores or rent. The problem, she said, was that a few months earlier she had walked in on Cersei having sex with her father.

According to her post, the affair had not been some one-time shock. Once the truth came out, she learned it had been going on for as long as she and Cersei had lived together. She also said she eventually realized one of the reasons Cersei had moved in with her in the first place was to be closer to her father. That was the detail that seemed to make the whole thing feel even more twisted. It was not just that a friend betrayed her with a married man. It was that the married man was her father, and the friendship itself may have been partly built around access to him.

She wrote that she cut Cersei completely out of her life after finding out. Her father, in her words, was “obviously also complicit,” but the family situation around him was harder because her mother was staying married to him. That left the daughter in the ugly position of trying to keep functioning around the wreckage of the affair while also knowing she might suddenly have to work professionally with the woman who helped cause it.

What made the situation even harder was that she was not dealing with some random corporate hiring process at a huge company. According to comments preserved in the BORU thread, she worked in a field tied to her schooling, and this specific job was one of the few that lined up with Cersei’s graduate program and would give her credit in the right area. She said that was part of why she did not immediately assume Cersei had applied just to target her. At the same time, she could not imagine how she was supposed to act normal around someone who had lied to her face every day while sleeping with her father.

In the original post, she was trying to figure out how honest she could be with her manager. She said she did not know whether she had “grounds” to say anything, because from a purely technical standpoint Cersei might still be a decent fit for the role. But she also made it clear she did not trust herself to interact with her without rage taking over. She joked that she might go full “Septa Unella SHAME” on her, but underneath that humor was a pretty serious question: how do you explain to a boss that someone may be professionally qualified while also being completely impossible for you to work with because she had an affair with your father while living in your home?

The comments that followed pushed her toward the same conclusion. A lot of people told her this was not just ordinary “personal life” drama that happened to overlap with work. They pointed out that Cersei allegedly moved in with her, used the friendship, and maintained the affair behind her back the whole time. That, in their eyes, said something about judgment and boundaries, not just private morality. One commenter put it bluntly: they would not necessarily refuse to hire someone just because they had an affair, but they absolutely would question hiring someone who moved in with a family member to get closer to the person they wanted.

She also seemed to be carrying a lot of misplaced guilt about the whole thing. In one comment highlighted in the BORU thread, someone pointed out that she sounded like she blamed herself because she had introduced her roommate to her father. But as that commenter wrote, introducing a roommate to your family is normal. The betrayal came from the people who chose to exploit that access, not from the daughter who happened to let a friend into her life.

By the end of the post, the woman had not fixed the situation yet. She was still standing at the beginning of it, staring at a hiring decision that threatened to reopen a family wound she had barely started to close. What had started as an ordinary request from her manager — tell us if you know any of these candidates — had suddenly become a choice between staying quiet and pretending she could work with the woman who helped blow up her family, or telling the truth and risking all the fallout that came with it.
