Might Of Messed Things Up With A Friend? So about a month ago I came out to a close friend. (He's the first person I've ever came out to.)

This is gonna sound lame, But I came out to him over Xbox Live.(It's summer and he lives real far away)
After I told him that I was gay, he told me that it didn't matter, and that he was okay with it. He also said He might be Bi.

After I came out to him, He'd always check up on my (Text, call, IM etc.)
But now he's kinda stopped talking to me, He did call me the A few days ago, and then asked me if everything was okay, (I guess he could tell something was up cause of the sound of my voice.)

The thing I don't understand is that he's pretty much distant from me.
Barely talks to me, I don't really know how to explain it. did I make things awkward between us?
I dunnooo, maybe i'm overreacting..
