How do i know if he likes me?

Im having trouble. My best guy friend says one of my friend likes me. But my best guy friend doesnt actually know, hes just guessing. Wht are some hints or things he might do so I know that hes into me?

if he teases u. that's one hint or clue. but only in a joking kinda way. not if the teasing is mean.

try obvious flirting, but don't make yourself look like a bimbo lmao. He he responds with flirting back, there you go (:

Flirting:
. teasing you
.complementing you
.smiling when around you
