i like a gril,but she dont not like me,what shuld i do

1.if you really like her and you can't live without her,then try your best to attract her and let her konw that you are a good boy.2.if she still refuses you,don't feel sad,because it is her pity without you who likes her so much,and it is your luck without her who doesn't like you 3.time is the best doctor,time can make you learn a lot,and time can change everything.In the future you will find she is just an ordinary girl and there are more girls better than her.Just as the saying goes:"There's plenty more fish in the sea"(天涯何处无芳草),I'm sure you will be popular with many other girls if you are brilliant.So try hard to improve youself.最后给你一句中文：有缘惜缘 无缘随缘.只要自己努力过,其他的交给老天吧!
