She will come up to you, and wait for it……………………………………………………………………………keep waiting……………………………………………………………
Ugh just go on ask her out if she says no just cover it up like say "I KNew u we gonna say that I'm just askin"
Honestly you look completely desperate . If you're at high school you should know how to approach a girl , no exceptions. If you honestly want to know this use google or some other bullshit but not a game :/or maybe even try asking your friend
If you like a girl just tell her. That's what I think everyone should do. Be honest and if she doesn't like you back at least you'll know. Not to be sexist but I don't think she'll judge you for it. Anyone who's that honest earns my respect.
If shes a slut then you will know she in to you, if she has confidence issues then you will find out many years down the road and if shes just a lil shy her/your friends will let you know. now get some zit cream and slap on those dr dre beats headphones on and get prepared for Boom Boom
