Inn for a girl i barely know to ask alot about my dead firstborn?

A year and 8 months ago, i met this girl named Ana. Ana is not you're average girl.

She lies, she listens, and she repeats what she hears as her own story with such intense yet somehow over-dramatic emotion and detail.

But she reveals very little about her true self.

Anyway, she latched on to me, then, very eagerly, "because we have the same birthday" same day, month, year, and only 3 hours apart.

I thought it was cool too, dont get me wrong.. but she WAS ECSTATIC.
She told me how her mom was always shady with details of her being born and that she always wondered if she had a sister. and we "look alike!"

I KNOW WHO MY PARENTS ARE. And they are both dead and buried..
This girl cant be serious.

So she's crying over my shoulder, meanwhile im comparing us.
-She's like 5"11 and nobody in my family is taller than me. im 5"2. (except my dad, he was 5"6)

She's chubby and thick as hell, im not and nobody in my family is. Me my mom and my REAL sister all have the same body type. Literally. Short, small waist,same skin tone but my sister looks more tanned) little extra belly fat (babies hahahaha) beautiful face, long hair although mine is very curly and black (african dad), while theirs is straight as a pin and dark brown/burnt red)

So our only similarities is curly dark hair (tho hers isnt very curly unless wet, its more straight-ish) and small chinky eyes.

Shes from Dominican Republic and i was born in san francisco, cali.

BUT SHE CAN SIT IN MY FACE AND CRY! ABOUT HOW WE MAY REALLY BE SISTERS, FOR REAL, oh my god, OH GOD, WE'RE SISTERS!!

But she's dead serious.

ANYWAY ANYWAY, a few years ago my 3 month old died in the crib during the night.
So we woke up to a nightmare with no escape. And as terrible and dark and HARD as that was for us (as in me and my boyfriend (My tribe forbids me from marrying since both of my parents died before the age of 14, young adulthood)) we eventually coped with it.. or so it may seem anyway.
I learned not to think of the bad memory, as opposed to thinking of ALL the other memories. Or to just not think about it at all, or very little. As i havent fully coped, i mean WHO CAN?

....

Anyway, every time i talk to her (not often, heh) she ALWAYS brings up my son. ALWAYS. And not like "oh how was birth, do u have strechm blah blah" NO ITS LIKE, "So hows your day, omg i missss you! hows your baby? DO YOU MISS YOUR DEAD BABY? LIKE HOW WAS THAT? LIKE HOW DID YOU FEEL HOW DID YOU KNOW HE DIED, DID YOU WAKE UP AND FIND OR DID YOU DREAM IT OR WAS HE BLUE?
But then she tells me some minute detail about me, gloating about how good her memory is..

Like whhhhhhaaaat the fusc?
I can tell she means no harm. Shes a nice girl. But i mean jeez, she wants to hear the story every. time. we. talk.

I answer in awkward chuckles and mumbles and she just goes on and on, no matter how i answer.

Sorry for the story. I just wanted yall to get a good understanding of how scary she is.

*****Is this girl normal? **** Should i avoid her..
