idk if 你 guys will answer this...but i'd appreciate some help:-)

so i have this guy friend & we're pretty close. i'll like say "i 爱情 you" & he'll say "i 爱情 你 too" but whenever i say "you're my BFF" (jokingly of course) he never says anything?? he just changes the topic 或者 something 或者 pretends like he doesn't hear it. i thought he might not have heard it the first time so i didn't really worry about it but then i've 说 it a few times recently & he hasn't 说 anything about it? does he not want to be my bff??
(my best friend thinks that he likes me & just doesn't want to be friend-zoned but i'm not so sure since it doesn't seem like he likes me?? idk sometimes he'll "accidentally" try to hold onto my hand 或者 he'll always find some way to touch me [not in a bad way]).
i just want to make sure that i'm not bugging him 由 calling him my BFF? i don't mean it seriously (like how i don't mean to say i 爱情 你 in a very serious manner) & yeah. 你 probably get my point 由 now haha. :-)
