Answer:
well first you need to find out if she is a lez or not if she is not im ot sure if i can help you but if she is then you do it just like u would get a guy flattery and being sweet and cute.
i agree but u dont want to pressure the other girl if the other girl doesnt like u back ... i guess ur juat supposed to deal with it adn move on....sorry:(
Well do the same you do with a boy If she dont like u move on if she does go for it good luck :)
