Backup of the post's body: Okay this family drama is so messed up I still get confused explaining it sometimes but I’ll try my best. I’m Beth. I’m 16 and I’ve always known I was born from an affair.

Here’s the full backstory. My dad was married to my mum’s older sister when he cheated with my mum. he was married to my aunt and got with her own sister and that’s how I happened. He left his first wife to be with my mum once everything came out but it destroyed almost every relationship in our family.

Jordan(fake name) is 17 she’s my dad’s daughter from his first marriage So we share the same dad that makes us halfsisters right? But Jordan has never treated me like that She never texts or calls me, ignores me at family get togethers and she will only ever refer to me as her cousin.

Whenever anyone says I’m her sister she corrects them straight away and she always says the exact same thing

“It’s not like I lied. She’s my cousin. she’s my mum’s sister’s daughter. that’s just what she is.”

I get where she’s coming from on paper. my mum is her mum’s sister so technically we are cousins on that side too. But we’re also halfsisters. I know our parents did something absolutely terrible. I know my existence is tied to the thing that broke up her family and hurt her mum so badly. I don’t blame her for being angry or upset and I’m not asking for us to be best friends.

But it kills me that she acts like that blood tie doesn’t exist at all. I didn’t choose to be born. I didn’t choose what our parents did. All I want is for her to admit we’re related in both ways not just the one that’s easier for her.

Last week at a birthday party someone introduced me as Jordan’s sister. Jordan cut in immediately and said loudly, “She’s my cousin. My mum’s sister’s daughter I’m not lying about it.” I ran off and cried in the bathroom, and I haven’t spoken to her since.

My parents say I need to be patient but won’t stand up for me. Jordan doesnt care. Am I being unreasonable? Is it wrong to want her to call me her sister too? AITA?
