AITAH for telling my sister that my kids won’t ever be allowed to sleep at her house if she marries her fiancé?

A woman is standing firm after her 27-year-old sister announced plans to marry a man she met just two months ago—who openly admitted serving 12 years for m__der. The whirlwind romance has the sister ring shopping on date two and venue hunting already, despite the horrific details of his crime uncovered online.

When confronted, the sister accused her of being unsupportive and judgmental. In response, she made it clear her young daughters would never sleep over at their home due to safety concerns over his violent past. Now questioning if protecting her kids makes her the asshole, she’s torn over the rift it’s causing in their close relationship.

‘AITAH for telling my sister that my kids won’t ever be allowed to sleep at her house if she marries her fiancé?’

The relationship started innocently enough on a dating app:

My sister (27f) met a guy almost 2 months ago on a dating app. Within their first phone conversation he told her that he served 12 years in jail for...

Apparently the story he initially told her is that him and his friends were trying to rob a guy and it went wrong and they ended up k__ling him.

She told me and one of her friends immediately after their phone conversation so we searched his name and found the articles and court documents and were horrified with the...

But she continued secretly:

Rushing into marriage after mere weeks, especially with someone disclosing a violent felony early, raises serious red flags for manipulation or love bombing—tactics often used to isolate and control. While rehabilitation is possible, trust must be earned over time, not assumed.

Relationship expert Dr. Ramani Durvasula notes on narcissistic abuse patterns: “Intense early idealization, rapid commitment pushes, and religious conversion appeals can mask deeper control issues” (source: insights from her work on toxic relationships). Here, the speed and history combine dangerously.

As a parent, prioritizing child safety over adult sibling harmony is non-negotiable. No reasonable person expects overnight sleepovers with a recent ex-convict, reformed or not. Boundaries protect kids without judging redemption outright.

Supporting the sister means expressing concern lovingly while holding firm—her hurt feelings don’t override parental duty. Long-term, this could save her from harm if instincts prove right.

Here’s what people had to say to OP:

The response was unanimous: she’s emphatically not the asshole, with many praising her protective stance and warning of dangers:

This whirlwind romance laced with a murder conviction screams danger, and setting hard boundaries for child safety feels like basic parenting to most. The sister’s hurt doesn’t change the risks—rushing marriage with love bombing and a violent history rarely ends well.
