What does it mean when you grab a girl's waist?

Im a girl and there is a guy 10 years older. he asked me to dinner just me and him then he brought me to his old apartment rooftop to watch the stars, then I can feel him grabbing my waist a couple of times. could this be just a friend thing? he also grabbed my hand because he had a mind change on where to eat - we were on the subway and there were a lot of people. (one subway station earlier)

we ordered some light alcohol but my cheeks are getting red so I use my hands to touch my cheeks and he started touching my cheeks to see if my face is hot (temperature) not once but twice
