Questions: Girl's Behavior

I saw this guy I'm secretly crushing on in the hallway from afar and acted as if I didn't see him. Just as we are about to pass by each other I look at him and the second I do he looks at me and we made eye contact. We've never talked to each other but I really want to get to know him. Is this a good sign? Did he purposely look at me to respond to me initiating the eye contact or was it just a natural reaction? I personally wouldn't look at someone I didn't find attractive even if I knew they were looking at me. I'd avoid eye contact at all costs just because I don't want the person to be getting the wrong idea. What about you guys?

That was my first ever eye contact with him. I've never made any kind of communication (verbal or non-verbal) with him. I'm not worked up or over analyzing or anything by the way. Just curious so I know if I should or shouldn't pluck up the courage to send off more signals to him to show my interest :)
