This reminds me of a guy who wrote in to SSM who grew up in the 70s; he knew a swinging bisexual couple who used to throw sex parties. The wife got addicted to the experience, the husband enjoyed it at first but it ended up ruining him. While the husband tried to get his wife to stop, she couldn't and didn't want to because her brain was already rewired to be a non-stop whore.

Over time it completely broke the husband, so he moved all his assets elsewhere, took her out of his will, and made sure she couldn't have access to any of his finances, and then he pulled a chair right at the front door and blew his brains out with a shotgun. The minute she opened the door to bring one of her lovers back to their place, his decapitated body was the first thing she saw.

Since she was locked out of all his assets/inheritance/etc., and after seeing that horrific scene, she not only lost her mind, but she became destitute because she had no finances and no assets and could no longer afford to stay in the house.
