AITA for refusing to share my food with my wife after she repeatedly orders food she doesn’t like?

We’re a working couple in our late 20s. Often come home late, around 7 PM, so we regularly dine out, like 2 times a week. Our country has hundreds of dishes, so we’re never out of options.
I prefer ordering familier items and try something new only when it’s looks too tempting. I’m a sensitive eater (not picky) as I’ve strong sensory sensitivity. I get nauseous easily if I eat or smell something I don’t like.
My wife is totally opposite. Half of the times, she tries something new and orders things just by reading their names. Mostly, she doesn’t even know how her order looks like.
And mostly, the food she tries isn’t good as our comfort food. So after 2-4 bites, she asks me to split and share each other’s food. I always hesitate doing that due to my different food habits as mentioned above.
She’s aware of my nature but asks me to share anyways. It’s been 3 times in a row, the food she ordered came out totally bad and I had to give up on half of my food to compensate it, as usual.
Being fed up, recently I clearly told her that I won’t be sharing food from now and whatever she orders, it’s all upto her even if it doesn’t come out good. She agreed in a low voice.
Now yesterday, the same thing happened again and she casually made the same gesture of sharing food. I said no, mentioning our recent talk about it. She had to finish it all, it spoiled her mood and got passive agressive the rest of the evening AITA
