AITA for telling her what I actually like?

I (teen, m) was born with a platinum spoon in my mouth. Generational wealth to the point that my family quite literally owns half of the sim world. Our name is associated with several businesses. It's impossible that you haven't heard of it.

I'll admit for a long time I loved rubbing in everyone's face how much wealth my family had. I mean what good is generational wealth if it isn't a bragging point, ya know?

But then I met someone, and she told me something that my estranged older brother once told me, "I'd rather be poor and fully alive than rich and dead inside."

It didn't stick with me when I was a kid, I guess the reason it stuck with me now is I've found I have a real passion for an activity my mother would view as a hobby-- but genuinely I wish I could make a living at it. I want to.

I love my family, don't get me wrong-- but I've begun to wonder if maybe-- just maybe-- I shouldn't follow my mom's vocational pursuits, or law, or literally anything she'd deem acceptable. Yeah sure I'm good at math-- I don't struggle with it but-- I don't have a passion for it, if that makes sense?

What I do enjoy, more than anything-- is baking and cooking. So I'm thinking of going to culinary school or maybe pursuing a career as a food critic. Turns out the girl who said that to me-- well we're dating now, my parents don't know. They wouldn't approve of her-- but she's going to be an arts critic or a visual artist, she hasn't quite decided just yet but plans to study art history in university.

When I applied to university my mother sent me off to live in one of the apartments we own in San Myshuno, and oh my gosh-- the food here is incredible. It's not all high quality, but the variation in cultural presentation is off the chart. The aromas, the Asian neighbours down the hall always have the most intriguing smells coming from their apartment. The way the flavours all blend together in these ethnic dishes-- my mouth waters just thinking about it.

My mom was talking about me attending Foxbury Instutite, and I told her I wanted to attend Britechester culinary school. She flipped on me and screamed that if I did I'd never be welcomed back, I couldn't see my younger siblings and the only thing she'd pay for me is my rent for the next three sim years and then if I still won't accept studying economics or law, she'll cut me off completely. So I have three sim years to make this work and if I do I can stay where I currently am (honestly it's a pretty lavish apartment-- three bedrooms, three baths, it's a townhouse style apartment so there's a main floor and an upper level).

My Dad has stood up for me saying that if she follows through with disowning me he'll divorce her and take my younger siblings ("N" infant, m, "T" infant, m and "V" infant, f) with him. Yes, my mom had triplets, and the funny thing? While my older brother and I resemble our mother, the triplets all look like mini replicas of my Dad.

I feel like the family's at risk of falling apart all because I feel more alive now after figuring out my passion than I ever have before. My brother got in touch when he heard about what was going on and encouraged me to be true to myself, but-- AITA for telling my mom I want a career in culinary arts?
