Be lucky that you don't know how she turned out and that your feelings remained pure and wholesome. In 6th grade, I had this major crush on this one girl. She was perfect, blond hair, blue eyes, and athletic. In addition, she was very charming, funny, smart, caring and overall a wonderful person to be around. I developed a crush on her before even realizing it.
Over the course of the year, we got closer and closer together but right before I was able to ask her out (one of her friends told me that she liked me and dating was starting to catch on) I got the news that I was moving away at the end of the year and decided against doing anything.
She remained in my head as this perfect girl who I just never got the chance to be with, a memory that I cherished during periods of loneliness in my new school. I kept meaning to try and find her on social media or something and catch up on the times, but never got to it.
Anyway like a week ago I was able to meet up with one of my old friends from that school and found out, to my horror, that she became a landwhale feminist who keeps arguing with the school about putting in bathrooms for agender people, and in his words "became batshit fucking crazy."
