I have my pickyness. But its not crazy wild. I dated a fella once who was def more on the spectrum than I. My best friend at the time, but when we went to my favorite mexican place, and he ordered chicken fingers and fries.. cant say I loved that.
Dating a super picky eater, only made me realize how important it was to me (as a varied cook), my partner love food of variation, at least to a degree where you can find something on a menu thats not chicken fingers and fries.
To his honor, he did try a few things out of his comfort zone I cooked. But I cant live off pancakes, pizza and chicken fingers, especially when I was in my baby vegan stages and just exploring new flavors. I started liking onions and peppers, avocado and spicy foods, and my pallet was growing. Nothing wrong with thiers being stagnant, but it was a serious incompatablilty, and I am not even the most adventurous eater.
