Help me!!! iam a girl of 21 years old.iam doing my final year btech course.i had lost a friend whom?

i feel is very close to me...still i have the same love for my friend eventhough it was his mistake to have avoided my friendship because he was in love with some girl.he is a boy of our same batch.my friend whom i trusted a lot did not tell me that he loves a girl and myself and my other friend felt very bad that he did not tell us.he completely stopped contacting us.i did not speak to him for many weeks after i knew this until one day one of my other friend told me to talk with him.later on i decided to speak and he did not feel guilty of not telling us.rather he said that he thought we had known it.after few months he stopped that love but he did not tell that too..i was missing my friend all time...the girl whom he loved said sorry to me for she was the reason why he did not speak to us.alas....now i do contact but i had never got my old friendship back...i tried to solve this by asking him why and what is the problem..he did not give me the right answer..still i have my friendship to him but i dont feel he has.he shares nothing as before...i had cried a lot and lot for his friendship,he has never known... i couldnt leave my friend.he shows no care as before..how much i care he never does...sometimes i had thought of leaving this friend of mine but couldnt..can anybody please help me get this friendship back??????????please i miss my friend a lot....he is such a good friend..
