Family Betrayal from Sarkasmus

In my personal view, this is more of a regular cheating Wife story than Family Betrayal. But it keeps getting suggested, so decide for yourself.

Husband finds out his wife is cheating on him... with her entire family.

Rick's family was absolutely dominated by the women. So he fled and they don't understand why.

It's a long standing family tradition. But he just wasn't attractive, so they excluded him. I don't like the ending, but it's apparently being rewritten.

Son discovers his entire extended family is doing it, while keeping it a secret from him. Because, while refusing to explain themselves, he's NOT welcome to join.

Young man has enough of his parents' neglect and builds a new life with his girlfriend, who has her own set of problematic parents.

Guy gets abandoned by his family and, even after making his escape, is repeatedly beaten down by life. Not my personal favorite, because halfway through the story, the author seems to have forgotten major plot points from the first chapters.

Falsely accused of a heinous crime, his entire family immediately drops him like a hot potatoe.

Man suspects his wife is having an affair. He is quite surprised to find out with whom. There are quite a few alternate endings from other authors on here, that are all worth a look (if you liked this one).

Young Woman becomes the family-outcast, as her mother partakes in every male of the family. And they all refuse to tell her why.

Man finds out his wife wants to cuckold him. And she is supported by his parents, his siblings and even his children. The sequel is called "On the Lam".

After his wife's death, he finds out his entire family had fun with her.

His wife cheated on him from day one, even with his father. His daughters slept with his friends and colleagues. Finally, they decide to let him know in the absolute worst way possible. I don't like how the story ends, but see for yourself.

Story of a boy growing up, being forced to take responsibilities beyond his age. It's a little soapy, the parents' inability to "adult" is over the top, and the drama seems forced at times. But it fits the list.

Story about a boy being neglected and abused by his family for his entire life, while his sister is the princess. Then his sister suddenly gives him a BJ, so everything is forgiven and he falls deeply in love with her. It's crap, but fits the list.

He spent eighteen years in prison because everyone believed he murdered his wife and children. Caution: This story does not have a happy ending... for anyone.

Youngest Son is cast out, after his family stole everything from him. When he almost got back on his feet, they start their next scheme.

Son finds out his family has been having swinger-parties for years, and kept only him in the dark. Sadly, the first story ends with the confrontation and the provided separate ending-story makes no sense at all.

Brother steals his girlfriend and the family supports it in the worst way possible.

Brutally raped by his own family, a boy needs to learn to trust again. Caution: DO NOT read this if the topic triggers you. It is NOT treated in a way that makes sense.

An attempt at creating something akin to "A Broken Circle" by TangoPeru, that makes sense but also has a happy ending. First five Chapters are mostly setup.

A (sadly) very short tale of a husband reacting to the revelation of his family fucking around behind his back in a reasonable way.

Fat, neglected and beaten boy tries suicide but fails. Is sent to a farm where he loses 120 pounds in 10 weeks, learns martial arts, becomes so attractive he turns lesbians straight and inherits Millions of Dollars. Fits the list, but nothing makes sense.

Man recaps his discovery of his families' activities whenever he was sent away. Then he deals with the aftermath.

Wife gives husband a nasty STI... that she caught on one of her family gatherings.
