Um sorry but I wouldn't assume that just because a girl is nice to you that she fancies you! Siderla you should just show what an all-round-good-guy you are by accepting their friendship and be super friendly to all that lot. Don't ignore the girl you like but just act, indifferent. Maybe she'll realise what she's missing out on or maybe she'll feel the same but at least you get some shiney new friends out of it all
