Considering A Rift In Friendship

In my life, I deal with a variety of people. I call many my friend, and all have their own backgrounds, interests, and trials. Because I often feel I have no eloquence in my speech, I try to be very choosy in what words I use. It's my policy to listen to what a person has to say before I even consider giving any suggestions or advice. Often, I may not even express my thoughts at all. I have found that when I simply listen to the other person, I learn so much more about their thoughts, and what they are going through.
In dealing with my friends, today I was surprised to find them in a situation exactly like the ones in books, songs, and movies. It is not just the situation either, but exact phrases too, which causes me to groan inwardly, because it is only making it worse, and not better. It is hard being in between a rift between two good friends, and uncomfortable being the "middle-man," knowing that I am unable to fix the issue when one is mad at the other, but the other one has no idea what's going on.Yet all of the hints are there, so I really wonder if that person is actually clueless, or not admitting it to himself. There is a part of me that wants to clear it up, and just tell the clueless one what's going on, but I feel that will make it worse. It's hard to know what to do, and perhaps more importantly, what NOT to do.
At the moment, I think the only thing I can do is to not make it worse; considering that the conflict was set off by something I said . It does not make me happy that my friends are fighting.  If only people would be honest to themselves and to each other, but I also know that would bring it's own set of problems to the table.
