Does my best guy friend like me?

He's like a brother and very sweet and always making me laugh. We use to call eachother bf & gf as a joke cause someone thought we were flirting then he asked me if we were really dating but I didn't answer. And he calls me the most beautiful girl in the world & he said without me the world would end & I'm important & he misses me sooooo much. Does he like me? Cause I like him and what are some hints I can give him over text that I like him? Sorry it's long thank you! :)
