Author_Shizu To answer your question: I usually add a story I liked to my library after reading a chapter or two. Most of those times, out of misplaced optimism, I pause reading. Unless there were few enough available chapters that I could finish them all in one go, I usually think "this seems great so far, I'll read the rest later." If many readers are like me, I hope you can find some comfort in knowing they probably did like your story enough to want to continue.
As a writer, I understand your doubts. I started a month after you did, I've got around 20 chapters, yet my collection and views are not half of yours. My active and consistent commenters are playing at a whopping two these recent chapters, and I also hope to the high heavens that the rest of my readers are the silent types. For me too, comments, collection adds, and votes serve as motivators -- NOT to keep writing, but to keep posting chapters here. I can still continue writing even if I don't publish, the whole point of joining a platform like this is to interact with readers and maybe get feedback if the story's direction is still going fine or something.
Right now, I'm just glad I do have some readers who let me know they've read to the latest chapter at the time they commented. Many of them don't comment anymore after that. Makes you assume a lot of things, right? It can be really really difficult to keep your thoughts positive, but I don't hold it against them, I just refer to my own behavior as a reader.
Sorry this got long, just want you to know that from my perspective, your story's doing amazingly well. If you're no longer enjoying the act of writing itself, that's one thing, but if it's only the audience's actions that's bringing you down, then it will be a shame if you stop. Good luck...
