Knowledge is power, folks. This applies to everything including discoveries you might make about your partner.

This woman learned that her husband had been cheating on her with another woman for quite some time now. Rather than confront him directly as most people would do, she decided to quietly wait until the perfect moment arose for her to reveal exactly what she knew. 

Based on her account of the final months of their relationship, it's clear that things were going sour already. When she told her boyfriend that she planned to move out when their lease ends in March, he admitted to feeling totally "blindsided." She didn't say anything about the woman with whom he was having an affair, so he thought he had leverage here. Despite the fact that she had suggested staying roommates with him until March, he told he wanted her gone by the end of the month.

She proceeded to make other arrangements, and not long after she moved out, she finally met his new girlfriend. She moved into the apartment practically immediately after the author left. Despite her ex's insistence that there was not any overlap, the author knew otherwise.

When she ran into the new girlfriend, she told her the truth. It turns out that the girlfriend was never aware that the author had been in a relationship with her boyfriend. She simply thought they were roommates this whole times, and that the author was not comfortable with him having her over to their place. Well, you can imagine how the new girlfriend responded to that revelation!

  • While we believe that honesty is the best policy, it's hard not to admire how the author handled this situation. Sure, she probably should have confronted her boyfriend about his cheating from the get-go. Still, it sounds like both parties in this relationship are wildly immature. At least the author got to have some form of closure in that final confrontation with the new girlfriend. Again, we don't necessarily condone the petty behavior, but it is fun to enjoy from a distance as an objective third-party viewer.

  • FriendlyMum NTA and soooo he deliberately bought her to the market to "accidentally" run into you for an adrenaline kick. (Mainly because he's been feeding off adrenaline from cheating on you this whole time and now it's gone and the fun mistress is now a daily doldrum.....) and instead you turned it all on his head and he realised he wasn't in control this whole time... you were. Hilarious. Beautiful revenge, revenge is best served by living your best life!
