How do I know if she likes me?

*if she playfully smiles at you alot
*if she tries to hold eye contact with you
*if she bites/ licks her lips around you (most girls think guys find this sexy)
*If she plays with her hair around you
*If she finds excuses to talk to you
If she is shy
*she will act awkward and out of place around you
*she will try to make eye contact but might chicken out
*she might get embarrassed and turn bright red
*she will avoid looking at you unless you ask her something
if she is a tease:
*she will pretty much make it obvious that she likes you
*one way to know if the girl is a tease is that every girl will act differently around a guy that she likes. Watch if she acts shyer, more playful, or more outgoing around you.

Depends on the type of girl, most girls will tell they're best friends and be really really flirty. If you really wanna know ask the best friend. Of if the best friend asks you questions like subtle questions like if you like anyone right now and stuff like that. I know personally when I like guys almost everyone knows. So just relax and ask the bestie , she knows everything.
