Moving into your first home with a partner is supposed to mean building a life together, not picking sides over something trivial.

So when a woman refused to let her fiancé’s single friend sleep over without warning, he responded by calling her names and trash-talking her on the phone.

That’s when the cracks in their relationship really began to show.

Keep reading for the full story.

AITA for not allowing fiance to have friends sleeping over?

Me (27F) and my fiancé (27M) have been together for eight years and have a two-year-old boy.

We were living with family, but we have now finally moved into our first house.

But there are a few cracks in their relationship that have set the scene for some conflict.

My partner, I would say, is quite immature, or maybe, as he says all the time, I’m just too mature.

We’ve been here for two months, and his best friend has come over a few times.

This was all fine and good, until things ratcheted up a notch.

Yesterday at 10 p.m., he called me as he was coming from work to say his friend would be sleeping over on the couch.

I said no, he’s not.

He asked why, and I said because I said no.

To her, this intrusion would throw off their entire routine.

Me and my son wake up at 7 a.m.

They sleep until later, and I need the living room as it’s an open-plan kitchen.

It’s just awkward, and I don’t want it.

Now her fiancé is upset with her and starts hurling accusations.

He started arguing with me, calling me horrible names.

Saying the house is his, so he can do what he wants.

He says I’m rude and ungrateful.

It becomes clear her fiancé doesn’t think that highly of her.

He says this is why I don’t have friends, just because he knows I have like two friends who also have kids.

This friend of his is single and childless, like all his other friends.

I then heard him talk bad about me on the phone, and I’m really hurt.

I cried.

She feels completely betrayed.

My own fiancé, who should be the person I trust the most, is talking bad about me because I didn’t let a friend sleep over.

AITA?

This relationship most definitely needs work.

What does Reddit have to say?

If it were this commenter, they would be seriously reconsidering this entire relationship.

At a certain point, she also needs to think about her child.

This is about way more than just offering a friend a place to crash.

Is marriage really the best idea at this juncture?

He wanted a sleepover, she wanted sleep.

Protecting your kid’s bedtime shouldn’t make you the villain.
