idk if bạn 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 tình yêu you" & he'll say "i tình yêu bạn too" but whenever i say "you're my BFF" (jokingly of course) he never says anything?? he just changes the topic hoặc something hoặc 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 đã đưa ý kiến it a few times recently & he hasn't đã đưa ý kiến 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 hoặc 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 bởi calling him my BFF? i don't mean it seriously (like how i don't mean to say i tình yêu bạn in a very serious manner) & yeah. bạn probably get my point bởi now haha. :-)
