What Does This Mean? when a guy calls you different?

Anonymous
This guy I'm starting to get close with.. is helping me a lot! I've been having problems and he has helped me through all of it. I asked him why?.. and he said he thought I was different with a smile :) we talk every night, he checks up on me to see how I'm doing, I don't know I have a feeling he likes me.. I know this is not much details but what does it mean when a guy calls you different, that you stand out from everyone else?
