I feel like you just hate her and yell and scream at her whenever she does something

Nah this sounds like you were just looking for a reason to yell at her. don't be the step monster

You are definitely the a$$hole here. I think you should bond with your stepdaughter.

Treat her with respect and she'll respect you. Asking nicely works better than insisting/demanding. Carry on like this and you'll basically become white noise to her.

you really need to sit down and have an honest talk with her about why she feels the way she does. this can be a learning lesson for both of you, or you can be an ass, and push her further into the indifferent attitude she is displaying.

YDI. Narcissistic parents are the worst. I hope she goes no contact from you in the future.

My dude. It's a blanket. Calm down. Like, a blanket will not be harmed by being in a ball instead of being folded. Step back and identify what it is that's really bothering you that's not a flipping blanket.

did she rip it, or otherwise damage it? if no? then you are whining about nothing.

If this quilt is not meant to be used why isn't it neatly folded and packed away?

Why would people write YDI on this one? The brat was asked to neatly fold up the blanket and she didn't. She's showing no respect for her stepfather or the deceased. And she sounds like a heartless snot too based on her response about her mother.
