Does he have a crush on me?

So I hung out with my group of friends and talked with my super shy guy friend who I have a crush on. I noticed he was nervous and he had Snapchat opened, pointed at my username and said ”this is you right?” (He obviously knows its me since we have sent stuff for a long time. He then said ”I noticed your not very active”. This is true and I know he is even less active than I am. Does this mean he keeps an eye on my score and kinda thinks about me? Does he like me?
