if a girl love a boy,but the boy not,how can the girl do

First before you say you LOVE the boy, How do you define LOVE? how can you be sure you really love that person? it just because he care for you? I hope not... do you have standard in looking for your future partner? If your going in or enter into a relationship you should considering marriage. You should looking for a life time relationship. Thats the base for relationship. If you love a person what will you do? You care for that person, treat that person special and you want to be with that person. Thats the human instinct. All you do is for your own desire for your own, right? how about the wants or desire of that of that person for you? If you really care for that person you'll respect what he wants and do what he wants. Loving a person is serving him. Give him what he desire. And that person will appreciate you and will love you very much. I hope that will help.

I guess the girl should move on and forget the boy! You both need to be inlove to each other to have a healthy relantionship and a better future.

I suggest you just forget him and move on. This guy doesn't deserve your affection and it's extremely harmful for you since he showed some kind of sympathy(so called taking care) instead of love to you which mislead you to believe an illusion he might one day come for you but unfortunately that won't happen ever never!!
