How do i know a girl likes me?

Question

i have a crush on her

Answer 1

If she is the shy kind she probably just looks at you and looks away when ever you look at her or when ever you say hi she blushes or whispers hello to you . if she's outgoing she probably goes up to you and starts flirting. if she's a friend its going to be hard to tell.but she'll be protective when ever a another girl approaches you.

Answer 2

if she flirts back with you
