well ask 1 of her freinds wat she likes in a boy or u can ask her urself and if she does actullay hate u than go for another girl u like and if ur cute thisll work but if ur ugly and fat i cant help u there and this might help cause im a girl
Just go up to her and ask her straight on. The worst that's gonna happen is probably her explaining why she hates you, but in the end, at least you know why, right?
