Unfortunately as much as you hate it, you have to step back and just be there for him. He needs to make his own mistakes. I know you want to step in and protect him, but he just needs the support of his friend. I know all too well how much it sucks to sit back and watch someone you care for be with someone else, or just not feel the same way back. It hurts but you have to be mature about it and deal with it. Maybe things will get better, who knows. As for right now, continue to be his friend & support him. Let him live his life the way he wants to.
