When I was in year 8 (about 13 years old) I was in a class with a girl that was as tall as the male teachers and taller than any of the boys in the entire class. Despite this, she was dating an average-height guy who had a great personality.
Your height doesn't matter. If a guy says that you're too tall then he is missing out on potentially having an amazing relationship. Don't pay attention to any superficial people. When you meet someone who will care for you, you will meet someone who won't care about how tall you are.
I can't speak for the guy's cuz I'm a girl but if I met someone and I liked them I would care about things other than their personalities. My current crush isn't some perfect 10/10 superstar. She is average looking and has a lot of self-harm scars on her arms from back when she was younger. Thankfully she doesn't do it anymore. Yet despite her average looks, I find her more attractive than anyone else and I'm so happy whenever I'm around her.
