Immature Cancer Guys!!!

I was recently intoduced to this cancer guy whom they say is really sweet. We havent spoken since we were introduced but i always catch him staring at me from the opposite end of our table in our schools cafeteria, and i think he has figured out by now that I liike him. So now he comes over to me and my friends and says hi to the girl who introduced us, however he has been extremley affectionate with her, to the point where shes like whats up with him. I know he puts on a show for me, but why ?? Do immature cancers try to gain attention this way, and does he want me to chase after him because I definately wont be doing that. Does anybody have any advice??
