What’s going with him? How can I move on? I kinda have a crush on him?

I first encountered him at work, and we happened to be attending the same school at the time. He possessed an unpleasant demeanor, being both unkind and distant. After a few months, I made an effort to move on from the situation. However, I unexpectedly encountered him again at work, and although we never spoke to each other, I made a conscious effort to ignore his presence. Interestingly, during our time in school together, he rarely visited my workplace. However, now that we are no longer attending the same school, he occasionally comes to my job, albeit infrequently.

I didn’t mean infrequently I meant often but not as often
