I'm writing a novel with a Enemies-to-Lovers romance subplot, and I'm so worried about crossing the thin line of E-to-L and dating your abuser. Can anyone point me in the direction of some good resources? I've tried looking it up, and all I could find was websites basically advertising their own books, or saying "[x] book is a good book! Go read it!"

I've suffered emotional abuse by an ex so the last thing I want to do is normalize abuse, or worse romanticize abuse.
