Try putting yourself in his shoes.
You're already learning how hard writing a polished manuscript is, and you even have the significant advantage of having lived the story!
I can tell you from personal experience that getting close to you and your story is a wild ride, psychically speaking, even at the minor level I have participated.
I can also tell you from the correspondence that I and he have exchanged in the past, he simply got hurt in the process, and decided to distance himself from the source of his pain as far as is possible, as quickly as possible.
In my opinion you picked a fine writer, (I really enjoyed his manuscript even in it's unfinished form) but one who was not able to deal with the forces and personalities involved in this story. Heck, there many other people who have dipped their toes into this story, since I've been watchng it, and so many have either run away screaming or been forcibly ejected for "disloyalty" that personally I feel I have to take my hat off to the man, for managing to produce what he did under the circumstances for as long as he did.
Please don't shoot the messenger, I'm just trying to give his side as it has been presented to me, in the exchange of a few emails to at least build understanding, since he can't (or chooses not to) if indeed as would appear from the outside that building bridges is no longer possible.
