Is he interested or just being nice?

So there is this guy who is two years older than me and i dont know if he likes me or not i just want some advice. and if you think he likes me or just being nice.

Reasons why i think he likes me? -His parents have come up to my parents and told them he has eyes for me, That he would love to show me around high school (because we go to the same school, im a freshman, hes a junior.)

• His parents told my parents he is interested and wanted to meet me and stuff because we never really talked and we know eachother from a gathering.
• on the first day of school we passed eachother and he saw me and asked if i found my classes alright and he gave me a hug. -When he textes me he put smiley face, and he gave me his number. he told me to text him sometime

Why i dont think he likes me

• On the second day of school we passed eachother like 5 times and he didnt say a word. we were in the lunch line and he was like right there and he kept staring forward, and didnt say a word he was silent and didnt turn at all.
• He is into sports alot, and always hangs with his guy friends. -The third day of school nothing again -I texted him the third day of school and we talked for a little, but then he all of a sudden stopped answering me. and hasnt messaged me since.

I feel like im always making the first move by messaging him first and texting him and i want to know if it is even worth it. any advice would help.
