Is it a crush? Please help me understand

I know this person and I stare at them as if they're a painting, I find them beautiful and their personality is ok I guess but, when we were friends I always had to start the convos and irl they seemed to not acknoledge me much, but I feel like Im hyperfixating on them and I still think they're beautiful but idk if it's a crush or if I'm just hyperfixating on them because I feel like I also hate them because of how I always had to intiate convos and stuff.
Is it a crush or a hyperfixation?
