Tired of maintain a friendship

Friendship are just easy to start but hard to maintain. Or may be to say it's tired to maintain. Good friendship are built on mutual respect, an appreciation for spending time together and enjoying common interest. One of my friend wrote a displayed message at his msn. Needless to say, that piqued my curiosity and i called up asked a lot of questions. He answered me that i was think too much and it's actually nothing and just simply wrote something to see my re-action. He is my buddy, my closed friend. I simply want him to share with me the narrative of his life. But his answer just like such a purposeful cut to my heart. Now i really don care what happen to him anymore. I dont want to work up a dossier on him! He never appreciate on my friendship and i really found tired to patient and take care of his feeling anymore. All this time, i've tried my best to done my part as a buddy, as a closed friend! Finally... I gave up and i'm now announce that all concerns end right here!
