This guy I knew for a few months, yesterday he shook my hand and then he rub my shoulder and smile. after that, kelp his eye on me? What do this mean?

We knew eachother for 4 months, before he shakes my hand mostly all the time, he keeps his eye contact but, yesterday he shook my hand and he rub my shoulder and smile at me and after that, he kelp looking at me from a far.
