I've Got a Problem!

Okay so here it goes. My mom and her sister don't talk at all. If you ask me what the problem is, I wouldn't be able to tell you. Really I just think it's some stupid shit.

Anyhow, my mom has done so much for my aunt since she is the baby of the family. My mommy has taken her in, supported her, you know...treat her as a big sister should treat her little sister.

But like I said before, they don't speak to each other. I think it may sadden my mom so she made an attempt to call my aunt the other day. I guess she started the conversation off by saying her B-day was coming up soon and she was interested in renting out my aunt's boyfriend's club for it. She then moved into information about her resent marriage engagement.


A few hrs. later I get a call from my aunt. Here goes the convo:

Aunt: hey Ashmalli
Me: oh hey auntie ange, wats up?
Aunt: your mother called me today.
Me: really...that's nice.
Aunt: I don't know why she feels the need to call me.
Me: ahh, maybe she just wanted to talk.
Aunt: Yea, she was talking about her bday and her marriage engagement and really I don't care because i don't want to be apart of her life.
Me: (gettin' kinda tight)...ahhh so exactly what do u want me to tell her?
Aunt: If she needs the club, it's a business she doesn't need to call me and about her engagement, i don't really care. I don't want to be in here life right now.
Me: (officially tight as hell) Ahh..I'm gonna go now...my phone is dying. CLICK!

HOW DARE SHE?

So after i told my mommy and daddy all of this, they feel as though I shouldn't speak to my aunt anymore because after all, my mom was only trying to be nice and according to my mom, "you came from me and if anyone had a problem with your mom then you shouldn't wanna be nice to them."

But at the end of the day, she is my aunt and I'm not that type of person. Ya know? Like I couldn't just cut her off like that.

So I'm kinda lost as to what I should do. I have a 21st B-day dinner coming up and of course my mommy is gonna be there. I really wanted to invite my aunt but because of her present behavior I'm thinking I may not be able to.

so the question is:

Should I diss her because she played my mother HARD, or should I continue on with our aunt/niece relationship?
