Go straight up to him and apologise for being rude last time you met.
He may need space or time to himself, or he could be feeling overwhelmed or upset. It's important to respect his wishes and give him the space he is asking for. Communication is key, so you could try talking to him to understand his perspective better.
If you like him, why are wanting him to leave you alone? But if that's seriously what you want, just cross your arms when he talks to you (creates a subtle barrier between you), avoid him as much as you can, and if he doesn't stop, just flat out tell him to leave you alone. :)
