49 ch...uh, wow.
Chapters are helpful for organization, but I feel like you really don't need anywhere near that many unless you're planning your story to have somewhere in the neighborhood of five million words.
Maybe you should use just three or four chapters for now, and then create more only when you start having trouble keeping track of pages. You definitely don't need seperate chapters just to swap a few pronouns around in otherwise identical text, for instance, a lot of the others you have seem to be likewise just based on the character's gender if I'm guessing the abbreviations right.
The story looks very ambitious, it's awesome you're getting so into this, but usually it's recommended that newbies spend some time reading a few stories and browsing the articles, and maybe start out with a smaller scale story just to get a handle on the editor and structuring of a CYOA. It can be really easy to bite off more than you can chew, and epics are easy to burn out on if you go in without knowing what to expect. (It already looks like you're planning to make it all a hundred times harder on yourself by not bothering with scripting, and even if you do wind up with some massive word count, at least some readers are going to notice that a lot of it is copy and pasted filler...)
