Gym crush advice-?

Ok.. I’ve been seeing this guy at the gym for 6+ months now. I have a total crush on him.
It all started when I was having trouble holding 2 doors open (vestibule) for this older man with a walker- this guy (gym crush) ran over and helped me hold the doors open for this older man. (I thought that was so nice obvi)

Later I kept seeing him at the gym but didn’t think much of it. A few times I’d notice him and we’d make eye contact.

3 weeks ago I was running on the treadmill and he walks down this pathway turns towards me and just stares at me- then walks back past me and leave the gym. So my thoughts were, “oh! He’s trying to get my attention “

this happened 2x where I felt he was going out of his way to make sure I saw him and made eye contact with me.

A few times I was nervous and looked away quickly.. but now i keep trying to catch his eyes Bc I notice him but i feel like he looks away.

So my question is… did I make up his interest in my own head lol does this guy just think I’m a freak now Bc I keep looking at him, or what? Also- any advice appreciated.

Sincerely, the girl who might be creepy.
