AITA for telling my fiancée that her sister can’t stay with us going forward?

Imagine a birthday dinner where the candles are lit, the food’s hot, and then—bam—a sister-in-law storms out to trash a garden. For one Redditor, this is just the tip of the chaos iceberg with his fiancée’s family. He’s a Christian guy engaged to a woman from a devout Hindu clan—think separated parents under one roof, a sister hoarding cash in a house she won’t live in, and a mom enabling it all. He’s been cool with visits, but after temple tales and tantrums, he’s done hosting the sister.

It started with wild temple predictions—him cheating, him being gay—then escalated to the sister crashing at their place. He laid down the law: no more stayovers. She flipped, ditched the maid-of-honor gig, and now his fiancée wants an apology. Is he the bad guy, or just a man craving boxer-brief freedom in his own home?

‘AITA for telling my fiancée that her sister can’t stay with us going forward?’

Talk about a fiancé caught in a family circus! He’s juggling privacy with a sister-in-law who’s got anger issues and a temple-fueled vendetta. She’s banking cash while crashing their couch; he’s begging for boundaries. The temple drama—cheating prophecies, sexuality guesses—sounds like a soap opera, but it’s rattled his fiancée’s crew enough to call his mom. Yikes.

He wants peace and partnership; she’s torn between him and her kin. The sister’s garden-smashing meltdown and guilt-tripping stayover? Red flags waving high. He’s not wrong—home’s a sanctuary, not a hostel for chaos.

This is a classic in-law clash with cultural spice. A 2022 Pew Research study found 40% of mixed-faith couples face family friction (pewresearch.org/study). Dr. Susan Heitler, a marriage therapist, says, “Boundaries protect relationships—without them, resentment festers.” (psychologytoday.com/heitler). He’s wise to stand firm—counseling could align them before vows. Readers, how do you tame wild in-laws?

So, where’s this groom-to-be at? He’s drawn a line in the sand—no more sister sleepovers—and while she’s sulking, he’s not budging. It’s less about dogma and more about dodging a lifetime of drama. His fiancée’s caught in the middle, but apologies? He’s not sold. This could be a preview of wedded “bliss”—time for a heart-to-heart or a hasty retreat?
