My boyfriend got my little sister pregnant. While we were still together.
My sister is three years younger than me. From childhood until now, we’ve never gotten along.
She’s never admired me. She’s always seen me as her rival.
Whatever clothes I buy, she buys the exact same ones — but more expensive and flashier.
If I join any activity, she jumps in too. Her only goal is to be better than me.
This went on through our entire childhood and into adulthood.
When I started dating, she began openly flirting with every single one of my boyfriends.
She wasn’t subtle at all. It was shameless.
She would say things like, “If I had met you before my sister, you’d probably be dating me instead.”
“Too bad you got stuck with her.” I wanted to disappear into the ground.
When I confronted her, she accused me of being overly jealous and dramatic.
My parents always defended her: “She’s just joking. She’s the baby of the family.”
Sorry, but I know what a joke is. This wasn’t funny at all.
After that, I stopped bringing any boyfriend home. I didn’t want the drama.
Even though I love my parents, every family gathering with her turned into a disaster.
Everything changed when I met my most recent boyfriend. We dated for over a year.
It was serious, so I finally introduced him to my family.
I was naive. I thought my sister had grown up and would stop her games.
But I was wrong. From the very first meeting, she said:
“Bro, if my sister ever does anything wrong, just tell me. I’ll always be on your side.”
Then she sat super close, wrapped her arm around his, and laughed loudly at everything he said.
I could tell immediately — this wasn’t friendly. She was full-on flirting.
So I pulled her aside and told her straight: “Stop it. I’m tired. Please live normally and stay away from my boyfriend.”
She replied with a smirk: “Wow, sis, you’re so insecure. Even I, the little sister, am more confident than you.”
“If you did this to my boyfriend, I wouldn’t even care.” Well, of course — she’s never had one.
A month later, she called me excitedly: “I have good news! I’m moving to your city.”
Not only that, she rented an apartment in the exact same complex as us.
She started texting my boyfriend directly for everything — rides, furniture assembly, help with moving.
She completely ignored me. One day I asked him where he was going.
He casually said, “Just helping your sister with some stuff.” He didn’t even think to tell me first.
We fought constantly. I asked him to set boundaries.
He kept saying, “I’m just trying to be nice to your family.”
But his “niceness” should have been for me first.
Then the fateful day came. We were watching a movie in our apartment.
My sister barged in with a serious face and said she had something to tell us.
I asked what happened. She announced, “I’m pregnant.”
I was shocked. She had just moved here and I’d never seen her with any guy.
The only man she spent time with constantly was my boyfriend.
At first I didn’t want to believe it. I asked, “Who’s the father?”
She stayed silent, then looked straight at him and said, “You tell her… or should I?”
She dropped the bomb right in front of me.
My boyfriend turned pale, like he was about to faint.
She smiled with half her mouth, clearly triumphant. In her mind, this was her ultimate victory after years of competing with me.
I screamed at him: “Say something! Tell me she’s lying!”
But I already knew from his face. He finally muttered, “I know I was wrong…”
“But technically it’s only half a betrayal… since you two are sisters and share the same DNA.”
What kind of twisted male logic is that?
I immediately kicked him out of the apartment.
Luckily he had his own place right downstairs.
Then I turned to my sister: “Never come near me again.”
Now he texts me 24/7 apologizing, saying it was “just one mistake.”
I don’t believe him.
My family messages me too: “She’s still your sister. Please forgive her. Everyone makes mistakes.”
Sorry, but this wasn’t a mistake. This was a stab in the back.
My sister sent exactly one message — no real apology.
Because she did it on purpose.
I don’t know what will happen next.
If you guys want an update, I’ll share it later.
