It would be hard to change such a person until she can tell you the truth on the reason she hates you. Just be careful about her and don't hesitate to help her when she falls down or needs a hand in difficulty. Even when she push you into hating her, pray in your heart to learn how to control it.
If you can make her admit the truth about why she hates you, then you may be able to sort it out together, until then, just be careful with her. babli_Girl
