If your sibling spent their entire life making you miserable, would you bother telling them that you caught their spouse cheating on them?

This 19-year-old man has never gotten along well with his 27-year-old sister, mainly because she was hoping for a baby sister and he’s definitely not a girl.

His mom and dad had a hard time getting pregnant with him and had to undergo fertility treatments to bring him into the world.

“She knows this, and they said she really wanted a sibling until I was born a boy, and then her attitude about becoming a big sister changed,” he explained.

“All they did to help her accept me and all the expectations for her to get over having a brother and not a sister did nothing. She has always been a hateful bully.”

“She spent years making fun of me, calling me names, rejecting all affection and interactions I tried to instigate, and doing everything she could possibly do without getting into serious trouble to make me know she wanted nothing to do with me.”

When his sister was a teenager, she informed his mom and dad that she would leave him home alone if they asked her to babysit, regardless of what she got paid to watch him.

When his sister got married, he was not invited. His sister never gets him Christmas presents, but buys them for everyone else, so his grandma told her off, and she missed out on the holiday over the last two years.

Now that they’re grown up, his sister is the same. They do not hang out, and if he does see her, she’s nasty and rejects him. He’s come to live with this and doesn’t make an effort with her.

He does not feel compelled to be a great brother to his sister when she has never once treated him with kindness or respect.

“Which is why I never said anything when I realized her husband was cheating. They’re childhood sweethearts who started planning their wedding in high school,” he added.

“They married young and planned to start a family in a couple of years. About six months ago I saw her husband making out with another woman. Then a friend of mine saw him with that same woman a few weeks later.”

“When my sister did learn her husband was cheating, he threw me under the bus and told her I saw him and this woman together. So my sister was [angrier] at me than [at] her husband, who cheated. When she told our parents, they asked me why I would keep his secret like that.”

He responded that his sister has rejected him year after year, so it’s not like he owes her anything. His parents said that he had an opportunity to fix his relationship with his sister, and outing her husband as a cheater could have served as a moment for them to bond.

In his mom and dad’s eyes, this was his chance to show his sister he was on her side and protecting her. He simply highlighted to them that if he was the one being cheated on, his sister would be mocking him, so he’s happy he stayed silent and didn’t get involved.

“They’re suddenly acting like she hasn’t hated me my whole life and like things are so different now. They’re insisting I make this up to her so we can reconcile. But I’m just disappointed in their reaction to me after all she has done,” he concluded.

He’s left wondering if he was wrong to stay out of this mess.

His sister is a monster, and his parents are delusional. His sister has been on this planet for close to three decades, so if she’s still bullying him, that’s not going to change, no matter what.

His parents should never have allowed his sister to get away with what she did, and the joke’s on them for creating such a divided family.

He should be angry with his mom and dad, not the other way around.
