I agree with @braveheart29 on:

I think the story will develop and end organically.

I don't believe there is any reason we should be considering whether or not to further develop the plots, and to think about when we wish to end it. We just write down the words that come to mind. When the words stop coming for us to write down, the story will end.

Now, regarding your contributions.
I have been thinking long and hard about all you said, and have come to the following conclusion(s):

I very much enjoy writing The slaughterhouse alongside with @braveheart29, and I believe we've become quite a team. And 14 parts down the line, I don't see how another writer would fit in with the story, regardless of you having read all the parts. I believe yet another writer would not only present me with another challenging task of getting used to your style of writing as well as it would be difficult for the reader to now need to get used to not just 2 writing styles, but 3.

I have therefore decided I would prefer we finish the story ourselves (@braveheart29 and I).

This does NOT mean you need to silently sit in a corner. Contribution in the form of ideas, comments, constructive criticism and the like are always very welcome.

Should you write a part yourself, I promise to read it, but don't promise to continue on it.
