Why can't I let this guy go?

[Hello]

I joined this jiu jitsu class where I was the only girl. On my first day there the instructor was kinda mean to me and put me down in front of everybody and people saw that I got hurt. Then I got paired with this guy I think is really cute. (jiu jitsu involves grappling and laying on top of people). This guy was very patient and helpful cause he felt bad for me . He then bumped into my butt with his head and made a smirk and raised his eyebrows lol. And then he said "good job" to me when we finished and I developed this huge crush on him ever since. That was about 2 years ago. I continued attending the jiu jitsu class but this guy never approached me or talked to me or paired to roll with me (does that mean he didn't like me?). And I kinda was fighting a bit with the instructor sometimes in front of everyone and I think he thought I was annoying.
Anyways.. the only interaction I had with him was that one time and I just can't forget about him. I know that he moved 3 hours away from the city I live in for university this year cause I stalked his facebook lol (I go to a different university in my home town).
What should I do?

You may only have lust for him and want to get intimate.
Move on from him since he seems to be not interested in you.
Wait to find someone who loves you for real.
