am i invading his personal freedom/space?

like this guy. ( he knows that ) he said that he likes me but he is very confused about his feelings for me. we talk on the phone every now and then but when we talk we talk for at least 2 hours. but we text everyday. we text for hours. a week ago we text for the whole day. it was really cool. we are not bf/gf. just friends. sometime he text first , sometime i text first. is this bad ? am i getting on his nerve ? i text him a couple of days ago and then he text back a couple of hours later so i didn't text him again cuz i don't want to bother him. then the next day i text then he text right away.but i didn't text again. he even told me that it is okay to text him when he is in school. is this bad ? is it weird ? am i suffocating him. he also start to text first. i love texting him and i can't stop. he text me first

iam 17 , he is 2 years older then me
