Slightly older male coworker talks to everyone but me. Im disturbed by him now. What is going on?

He seems a bit shy but still he talks to everyone so really how shy can he be? Now me? I have self diagnosed aspergers and am extreme shy and people call me awkward. I get bullied by men at work. I fear this guy is not talking to me because he realizes im different and doesn't want others associating him with me.
