How to know if a man is inlove with me

How will I know if a man is inlove with me?
I met a wonderful guy while in a conference in Osaka, Japan. He is from Shanghai, China. I used to be so silent in the group, since I am a little afraid to say wrong things during the conference since all my companions were executives like me. Anyway, when he found out that I am an english teacher to Japanese students. He started talking to me and we became very good friends. I invited him to my students place and we wnet there together one night.

I think its too early to tell yet, and im no expert either, but if he treats you differently to other people, thats a good sign.
