Very good. Much more information to work with.
You’ll notice the narrative arguments found on Subtext look a little different. They don’t normally mention specific characters because the whole storyform (not just the MC) is needed to prove the argument. But that’s really just an aside.
Not because there’s anything wrong with how you have it, but just to make it simpler for myself, I’m going to reword it as “By accepting that Sadie doesn’t love him, Mitch is able to get his life back.”
From here, I’d start pulling out whatever points I thought I could find.
“By accepting that Sadie doesn’t love him...” This sounds like a Change to me (although, to be fair, the entire story could be Mitch accepting this and it finally works out in the end—in that case I’d change the argument to ‘keep accepting’) so I’ll go ahead and select Change for the Resolve. Does ‘accepting’ also suggest a solution of Acceptance? Or maybe a crucial element of Acceptance? Definitely something to keep in mind, though I don’t know that we need to lock it down just yet.
“...get his life back” sounds like it could be a judgment of Good. What do you think?
