I love girl since my school days from 5 years and she knows that i love her, ( please see details down)?

It's good ..but you should create a confidence in yourself ,you have told her every thing ,,then what nothing to fear and be shy and all.. don't think you are average and she is pretty cute and all.. if she doesn't like you mean ..she wont reply you by msg and all ..as she likes you ,she tells to change yourself this and that ,be calm and remember the days you talked boldly in school days.. as you said,.. be confident,be calm and talk to her make her feel good for you..everything be ok.. don't feel wrong of yourself ,don't discourage yourself as if you are look not good and all..even if other says doesn't matter .. you and her should be happy and unite is main thing ..you should face it with confident..what others can do if you and her have good understanding.. Go On .. and enjoy.. be happy ..
