This is a bit of a long read. The story is divided up into multiple parts, but it comes to a pretty satisfying conclusion.
Shorter version: Guy's sex life is stagnant: mediocre once-a-week sex. So he starts working out and getting in shape, his wife is still uninterested in sex. Finally he tells her about his dissatisfaction and she tells him that she's no longer interested in sex. When he suggests getting a divorce, she threatens to divorce rape him by getting her rich parents to foot the legal bill. So, the guy agrees to stay married to her, but they will be husband and wife in name only. He moves into his own bedroom, stops talking to her, keeps working out, and goes out without letting her know where he's been. He also secretly starts getting his affairs in order so that he can divorce her and lose as little as possible.
Not long after, his wife can't stand the fact that her in-shape, high-earning husband is ignoring her and going out at night. She starts doing everything she can to try and get back in his good graces. She begs him to give her another chance. He agrees, but gives her a list of expectations and makes her admit in front of her parents that she threatened to divorce rape him using their money.
I love stories like this. The guy maintains frame as well as he can be expected to, and it shows the effectiveness of dread game rather than the typical r/relationships response of "you need more/better communication!"
