Why do tall, cute guys prefer tiny, petite girls?

I’m a rather tall girl and I’ve NEVER had a boyfriend. Never dated or had relationships. I flirt with tall boys but they don’t seem interested or they go for average height or short, tiny girls. I asked this one guy I had a crush on to go to the homecoming dance last year, rejection me and went for a short girl and now their dating. He is 6’3 and she’s looks like she’s 5’0”.
My best friend is 4’10”, petite and I’m 5’10” and a bit on the bigger side but I’m medium size. I don’t understand why a lot of girls want to be tall. It sucks. Guys found me “intimidating” and “scary”. I’m a girly, beautiful and fashionable.
I’m so sick of seeing tall men with short women. My dad is 6’2” and my mom is 5’2”.
Guys my height or shorter flirt with me. I don’t understand. This guy that I’ve known for years and a friend of mine says he likes me but it would be weird to date a guy shorter than me. He’s 5’6”.
I have a new crush and he is 6’6” but he never looks my way. Help! I’m 17.
