She Adamantly Refused to Help Her Selfish Sister Who Got Pregnant After Cheating With Her Boyfriend. Her Mom Demanded She Be a “Good Sister,” but That Ship Has Long Sailed!

A young woman was betrayed by her sister, who slept with her boyfriend and got pregnant. He left her in the last trimester, and now her mother wants her to help her sister!

Unforgivable Behavior

OP (Original Poster) is a 21-year-old woman with a 25-year-old sister. Instead of having a strong sisterly bond, though, her sister did something to her that she couldn’t forgive: she slept with OP’s boyfriend!

So Much for Blood

OP said she accepted that her ex “wanted someone else” but felt it was heinous for her sister to betray her like that. She and her sister had once been very close, but as they got older, jealousy began to become an issue.

What She Wants, She Gets

Slowly but surely, OP said that anything she got, her sister wanted. If her sister weren’t given what she had, she would go out of her way to ensure she got it.

Unbelievable Sisterhood

After some time, OP found out her sister was eight months pregnant with her ex-boyfriend’s baby. She threw up because of how it made her feel to be betrayed by her sister like that.

While OP had maintained no contact with her sister, her family had become involved and wanted them to speak to each other again. OP couldn’t believe her family would ask this of her.

The Truth Comes Out

Soon after, OP found out that her ex had left her sister in the last trimester, which she only found out about because her mother “gossiped and let it slip.”

OP told her mother she didn’t want to hear about it, but OP’s mother insisted on telling her the whole story.

The Whole Story

Her mom informed her that her ex had beaten her sister, pushed her down the stairs, and fractured three of her bones. For some reason that OP didn’t understand, her sister had gone back to him after that.

Wild Turn of Events

OP had been with her ex for a while and couldn’t believe what she was hearing. He had never been violent toward her or shown any sign of violent behavior.

Not Her Problem

All this trouble had been at the start of their relationship, and OP hadn’t gotten involved. She didn’t care because her sister had betrayed her, and the two of them seemed to “want each other,” so OP stayed distant.

A Call for Help

OP said her sister had even called her after one of their big fights. Her sister had asked her to come over, but OP told her never to call again and hung up.

Getting Desperate

OP’s mother called her after all this and said her sister needed a place to stay. She couldn’t pay her bills and was getting evicted; she also had nothing for the baby!

True or Not

OP didn’t understand because they had plenty of time to shop, and before he left, her ex was paying for everything.

So, she told her mother she wouldn’t let her sister live with her, and they argued because OP told her mother, “She can come live with you.”

Bonds of Sisterhood

Her mother disregarded what OP said and told her that the two of them had to stick together because they were sisters.

OP got angry at that and hung up on her mother. She couldn’t believe what her mother was saying.

No One Cared

When OP’s sister betrayed her, it left OP depressed, and she battled mental illness as a result. Now, her family was doing everything they could to help her sister when they had ignored OP.

What bothered OP the most was that her mother gave her sister a new phone and phone number. This allowed her sister to call her, text her, and leave voice messages on her phone.

Try Someone Else

OP clarified to her mother that if her sister needed help, she should find her ex. Not only did OP not want to help her, but she was adamant about having no contact with her sister.

Any Last Words?

OP texted her sister and told her to find her ex, which made her sister angry. OP’s sister told her that she “wasn’t a real sister” and that this meant that OP’s sister would always be poor.

What Redditors Think

It’s clear that a lot of family emotion is being tied up in this story, but Redditors still came through with the clarity you’d expect.

One Redditor’s response was short and right to the point, “Not the a**hole. Hell no, no way. Sister and her progeny can live in a closet at Mom’s if that’s all the room they have. Not your problem.”

Another Redditor went in more depth to help OP out, “Not the a**hole. Document everything. Send one last response that you do not wish to be involved with your sister or her situation and any form of communication regarding the matter will be saved and filed for harassment. Your sister made a choice to get with your ex. She saw how he was treating her and continued to stay. You have kept your distance from her and made it clear you don’t want to be involved. Your sister does not have the right to push herself into your life when you have made it clear to her to respect your distance.”

No More, No Less

OP maintained her position and continued to refuse to see her sister. A Redditor made a keen assessment, asking OP to look deeper into her life.

The user said, “Not the a**hole. Cut them all off and change your number again. Don’t give it to anyone without explicit instructions that it is not to be given out.”

Did OP do the right thing by cutting off all communication with her family? Would you help out your sister despite what she did?
