What Happen...

This morning I logged in and saw him online, I imed him to say hello. He seem cold, distant. I was talking to him and he respond was one word or two. I felt strange and a bit sad. The guy I spoke to before was not in the im with me. I didn't know what happen, what I did, it was like he no longer wanted to be my friend. I asked him was it something I did or what was wrong. He said no, he just didn't feel like talking. I apologized for iming him and he said "yeah. aight, bye" and that was the end of the conversation if you can even call it a conversation. I feel like crying, I know it sounds so damn silly. But I at least thought we would have a friendship if nothing more. What Happen?...
