You should understand him princy when u have time it is not compulsory that he is also free in same time so not make pressure on him. It is good that you wanted to talk with him always but he may have other works so may not give u time. Thats why should make other frds if u wants to chat always then they can give u company. Thats the only problem u have now having only one frd. So it is normally makes u to feel alone whenever they are busy.
