The situation
I'm working together with 2 persons on freelance basis. I've known both of them for a very long time already. One of them is a relative, which is why he doesn't want to work directly with me (in fear of compromising our relationship). The other is a friend.
The issue
The friend is working directly with me. However, he's got no organisation-skills and is really all over the place with everything he does. This has caused the project we're working on to be delayed. He blamed me for everything leading up to the delay. Since I'm not in the mood for a discussion with him, since I don't feel I can get my point across to him that way, I accepted everything he blamed me for without much of a reply.
The possible solutions
Though I didn't reply, I do feel wronged, and am afraid that the relative will also think I'm messing up since he only heard the story from the friend's side. I can prove that I didn't mess up, as I have documents in which it states that I required parts from the friend before I can start, most of which he never gave me.
The question is, should I point out the fault of the friend to clear my name, or should I just accept it and try to fix it, because telling it might mess up the relation between the relative and the friend (and perhaps have even more repercussions I'm not aware of yet).
Edit:
Thanks for the replies so far. I have a feeling I haven't been complete enough, so I'll try to elaborate. I am able to see my own fault in the matter, as I didn't do things perfectly well the last couple of days. I admitted that as well. The issue however is that I'm also being blamed for not having started months ago, which is the moment I told the friend about my requirements before I could start. The requirements where clearly stated in a document. That friend however met barely any of the requirements in said document.
When I noticed (after repeatedly reminding the friend of the requirements) that I wouldn't be getting much more information than I had months ago, I agreed to start right away, filling in the gaps together as we go. Between the time we agreed to that, and the moment I got blamed for not starting on time, I did miss one agreement we made.
Now I'm blamed for missing the last agreement, to which I agreed, but also to not having started months ago.
Specifically: Should I remind that friend and my relative that I haven't started months ago because the friend failed to meet his end of the agreement, or should I leave it as is?
