How?...

I don't understand. I really don't. My friend, and my "brother" started dating, and supposedly, two of my best friends and I have a problem with it? NO. But does anyone listen in this crappy town? NO. I'm not going to sit here, and be talked down to, because of an assumption that's made about me. My day was going perfectly fine, and then I found out that someone I care about, all of the sudden hates my guts. It's been bothering me all day, and the worst part is, he's too stubborn to listen to anyone else, and admit that he's wrong. What do I do? I've never been in a "conflict" with him, and it would suck to start now...Ugh, & right when my Winter Break starts too...Bummer ):
