Brother Advice

[USFSDTAlum]

My brother and I are three years apart. I'm 25 and he just truned 22. I left for college while he was a freshman in HS, and have rarely been back to the house since. We don't have a very close relationship, but it is something I am trying to work on. However it seems that he thinks I go out of my way to piss him off constantly. I am very confused as to what to do about this. He acts perfectly normal to my face and then stews and posts about what a miserable bitch I am in his Live Journal that he links from his IM profile for all to see. In the last year we have had several moments that I thought were my showing interest in his life, and then he posts something about me. A couple months ago we were going somewhere together, and we was driving. He has this very tribal music on and I ask about, not that I really cared, but because I was trying to find some middle ground to have a conversation on so we didn't sit in silence for an hour. It was some African political music that his friend has introduced him to, and he was explaining the back ground of the guy. Honestly very interesting. I thought it was neat, and we both had a conversation about. Later that week he posts about how he played that music purposely to get me to comment, and made me sound like I had made racist comments which I never did! As I said I was just trying to get to know him better, this is my only brother/sibling. Well back in June at my birthday, I had mentioned something so boring I had read on his LJ again. He seems perfectly fine, blows it off. I thought again, especially with a public linking from his IM that it was ok to read his LJ as he had it linked for everyone to see. Well it promptly goes private. Bring us to this morning, I am up early was reading a link on another LJ from a friend and was like lets see if MIchael's (my brother) is back up. As of July it is. And in the last paragraph of his 1st re-public entry he mentions how it is coming back public again, even if that means his "fat, unholy bitch of a sister to nose around and bring up personal secrets at family outings". If I had thought it was private I never would have said anything, nor did he ever give me any indication, that I said something wrong. I am so tired of trying to get to know him and having my advances being taken poorly. And I'm really hurt at how much contempt he has for me!
Now, I have long let this not bother me, and just failed to cultivate a relationship with my brother as obviously he is just bound and determined to see my attempts at friendship through a bias and chalk it up to a loss. Except that in the last month, my uncle (a very very very close uncle) has had serious open heart surgery, and Tuesday my grandmother had a serious stroke. I feel that given these circumstances I should try yet again to renew a relationship with my brother. Though, its just so frustrating. Especially when he's writing to the world what a miserable person I am and I have no say in how he portrays me.
Sorry this is so long.
