It's somewhat "reassuring" that I'm not the only one in this situation for a weird reason, that I'm not the only one "guilty" of it. My only series, Among the Stars, has 12 chapters published over 32. When I got to write it, note that I wasn't planning on writing it but rather that I needed to, I just started putting words in a document and finished few weeks later with a very long novel. I didn't know what I would do with it, so I found Lush and started publishing it.
It's now been 6 months that I haven't published anything (only got back into it few weeks ago) and I feel so bad about leaving it hanging, considering that some people love my writing and wants me to continue. I even started writing other stuff, which make me feel even worse considering what I haven't finished. Although, I've decided that I would edit my future novels completely before starting to publish, so I do not leave my readers hanging again. This way, it would also mean that the chapters can be released fairly quickly one after the other, keeping the readers hooked as you release 2 to 3 chapters a week.
Personally, I love series, the fact that the author could take their time to develop the characters and the plot. Although, I definitely prefer to read a series once it is all published so I can binge it. Mirroring what Longing was saying previously, it's more difficult to keep track of the characters and plot if the chapters are released only sporadically.
