Sometimes you just don’t want to include people in small intimate plans with your family and that’s totally fine!

This mother wanted her kids to include their step sister and they just did not want to because they barely know her.

But things went too far.

Let’s check out what happened!

AITA for excluding my step sister and yelling at my mom?

I, 24 m, am the oldest of my siblings. My mom just announced that she is pregnant with her affair (now husband’s) baby.

I have disposable income.

Because of this, I like to spend a lot of it on the 3 oldest 18f, 17f, and 14m. (throughout the story I will just call them siblings 1, 2 and 3 respectively) this will become relevant later.

They were planning for some quality time together.

My bf and I had been planning a summer trip and I wanted to bring siblings 1-3.

I also wanted to make it very special for the oldest because she recently graduated and is now attending a t20 so I told her that she can bring a friend.

The trip is in 3 days but we planned to pick up them today so we can all go to my boyfriend’s mother’s birthday party.

Things got messy…

Anyway I went to my mother’s husband’s house to pick up my siblings and my step sister (15 f) was there. Now for more context my mom got re married like not even a month ago so I’ve only ever interacted with this girl like a total of 8 times.

As we are leaving my step sister(SS) asked where we were going and when we were coming back. S1:tells her about the trip. Ss: asks if she can go. I tell her no its too last minute.

His mother wanted him to include the step-sister…

My mom: why can’t you take her?! your flight doesn’t leave for 3 days u can get another ticket.

I then said again that it was too last minute

My mom: if u have money to bring s1’s friend why can’t u bring your sister?

SS: starts to cry

My mom: blames me for ss crying and asks again why I can’t bring her and if ss can go instead of s1’s friend.

I respond with This is a present for s1 also I’m not going to cancel on her friend.

That’s a lot of drama…

My mom: you need to put family first I respond with, I barely know ss and she’s not even family to me (my mom then starts crying and pulls the how can u stress me out like this i’m pregnant card.)

I respond with I honestly don’t give af about you being pregnant when you shouldn’t even be pregnant at 42.

my mom: cries more and says I need to treat all my siblings the same and its unfair to single ss out.

S1-3 don’t deserve more than my other siblings and ss.

I respond to that with ss wouldn’t have even felt singled out if you hadn’t made it such a big deal also s1-3 are all fully related to me and imo do deserve more.

He didn’t want to argue any longer.

I left and the whole drive my mom was calling and texting me non stop.

I called her back and she started yelling at me saying that she is going to tell the police I kidnapped her kids.

I told her I have text proof of her agreeing to let s2/3 on the trip and if she even tries to escalate this further I will go to the cops with all the neglectful things she has done to her kids.

The mother kept threatening him.

The past couple of hours she has been basically been calling me an ah for not making my ss feel welcomed, treating my younger siblings unfairly and putting her through stress while pregnant.

I did feel bad about putting her through stress and feel that maybe I shouldn’t have gotten so angry in front of ss.

idk am I the ah.

Yikes! Why can’t the step-sister take the very obvious hint?

Maybe she wants to bond but it seems more unlikely now!

Let’s find out what folks on Reddit think about this story.

If the mother considered her own children’s point of view along with the step kid, it wouldn’t have gone this far!

What a crazy lady!
