If your story does not follow our Community Guidelines, it doesn’t mean we don’t want to publish it—it just needs a few tweaks before we can do so.
If your story was sent back to you for edits, you should have received an email to the address associated with your account, which will give you a little glimpse into the guideline that your story needs a little help meeting. Then, when you open your draft, you can click the black "Not approved" bar at the top of your story—that bar will unfurl to show you the moderators' notes on exactly what edits need to be made in order to get your story published.
