Is he a playboy or am I just overthinking?

so i've been having a crush on this guy for a month now, a few weeks after i knew him he sometimes would be "doing stuff", such as, playing with my hair, touching my shoulders, using his leg to come against mine, etc. but there's even one time when we were sitting together and he put his head on my shoulder, but I don't know what does these mean, cuz he does these with other girls too...
also we've been snapping each other for a week now and most of the times his snap score keeps going up but he hasn't opened my snaps, does it mean he doesn't wanna talk or what? i am confuseddd. GUYS PLEASE HELP ME OUT HERE, I DON'T WANNA WAST MY TIME.
