Torn apart

I feel like I'm being torn apart. A close friend of mine seems to be unreasonably very angry with me. I don't know why, or rather I know exactly why and there is no basis for him to be mad. I'm afraid that if I don't apologize and say I'm sorry (for something not even remotely my fault) he'll be mad forever. And I just don't want to do that because he already has the "I'm always right" complex and it's caused problems before. But the fighting stuff makes me insanely sad. I wish it would go away. (sigh)
