Haven't liked anyone in 8 years, is there something wrong with me?

I haven't sincerely liked someone since middle school. I'm not talking about love. I'm talking about a strong crush. Back then I was so nervous around him, I'd shake. My heart pounded when I heard his voice. I loved stealing glances at him from afar. He rejected me coldly and the experience was a bit traumatic for me.

Since then, I haven't had a crush like that. I've been in love (unrequited as well, went on for ~4 years). I've been briefly infatuated with online pals, but I haven't experienced anything like before in 8 years.

Am I misinterpreting what feelings are normal to have? Or is it strange that I haven't liked anyone seriously in so long? Is there something wrong with me?
