Aitah for telling my sister she has a different father than mine?

My mother is a narcissist.

And I’m the black sheep of my family.

So, everyone basically hates me.

This woman and her sister got into a little fight.

Well, the other day, my sister annoyed me by telling me something awful and offensive.

I said, well, at least, I know who my father is. My mother says she doesn’t know if you’re my father’s daughter.

Dad passed away, so we can’t ask him.

She remembered some details about their past that her mom revealed to her.

But when I was 8, I remember my mother cheated on my father.

She even told me to speak on the phone with the guy to say hello.

After a few months, we moved states and my sister was born.

My mother, along the years, always reminded me, we don’t know if your sister is your father’s.

She used this information to hurt her sister.

That was always in my head, and so I blurted it out to hurt her the way she hurt me.

My mother never said don’t tell your sister or anything, but it’s clear she never told her.

Now, my sister won’t talk to me and says she can’t believe I would make something like that up to make mother look bad.

She clearly lived a different childhood than I.

I wonder who her sister’s father really is.
