I think my god brother hates me?

Ok, I'll try to keep this short for you guys. I have only sisters and I'm the oldest out of all of them. I have one god brother that I consider my real brother, because we were so close. The thing is when I was little he used to call me up to his room and ask me if I wanted to watch something nasty. It was actually , but I didn't know that when I was younger. I used to watch it with him. My mom found out and forbid me to ever see him again which hurt me and made a lot of sense at the same time. I have not talked to him since. But recently I looked up his name on myspace and added him as a friend. I e-mailed him to see if he remembered me, he answered yes and then asked how I've been. After I responded he pretty much never said anything back to me. I know it can be annoying but I've always wanted an older brother to talk to and be friends with. So I check up on him every once and a while to see what he's up to. All he says is sup. It's led me to think that he thinks that I did something wrong or he's mad at me for some reason. Does he hate me or am I just going mad. I forgot to mention that I have not seen him in I don't know how long. But the last time I remember seeing him was when I was at my god mom's house for my sisters birthday. He spoke. I think that was about 3 years ago. I don't consider that even contact at all so the last time I really saw him and spent time with him was when I was about 6 maybe. What should I do?
