You could try some friendly affection and see how she reacts. Try giving her a kiss on the cheek. If she goes "Ew!" and pushes you away then she either doesn't like you in that way, or she isn't ready for that kind of relationship.
You could also try subtly asking her how she feels about homosexuality and lesbianism and find out if she's ok with it or if she's repelled by the idea. If she's ok with it you could ask her if she's ever had a crush on another girl.
If she's cool then maybe you could just ask her if she likes you.
it depends on the way she reacts to you most girls are easy to tell in that situation. if she is bubbly and likes to talk to you then most likely she does
you hook up the girl that he likes with the boy that she likes or you an just kill her if she likes him back BY DARK SOUL
you have to tell her its only good to do and this is from a girl.good to help.
wait......................................
Gather your wits and tell her how you feel.
Just tell her you love her.If she really likes you back she will love you to.
Maybe you should wait a little and see if she likes you if she likes you ask her out.
just tell her you gotta trust that she likes you back
If when you say hi she giggles or smiles or both
i think that sometimes they stare...alot.dont look back and if she keeps staring wave.if she waves back with a dreamyish look she probabley likes you.
You come clean and tell the girl you like's brother that it wasn't true unless she told you she likes you.
Just get talking to her about something she is interested in and see how it goes. Tell her how you feel about her.
your best bet is to tell her that you like her
