Strangers forever? Why won't he talk to me?

So me and this guy has a similar circle of people. So we see each other a few times per month. But everytime I’m around him. He will literally walk right past me and not say anything. If I’m talking to other people in the room. He will literally stare at me and watch me interact with them.
its so strange because his best friend speaks to me. And sometimes he goes out of his way to speak to me.
before y’all start i have tried to speak to him. But he will hurry by me so fast… i just dont get it. It makes sense for us to communicate because we have similar circles. He’s the only person I've never spoken with.
It’s to the point where i feel like maybe i did something to him? But i dont know what?
Making a friend has never been this hard for me. It’s starting to bother me hence why I’m in this site asking ab it lol
