What do you consider cheating in a book?
Is it dependent on the trope at all?
If a couple hooked up and then became enemies, and each moved on or had one-night stands, is that cheating?
If they met and had a date but no sex, and then came together later, is any sex from the initial meeting considered cheating?
If they were nothing more than tension relief and didn’t know anything about each other, can they have sex with anyone else in the book after that or is it cheating?
I personally have a very different view on book cheating versus real-life cheating, but I also have different trope acceptabilities too. In a book, if they are not a couple, there was no expectation of exclusivity, and they were not at the L station, then it’s not cheating. Shitty behavior, probably, but cheating, nah.
What do you think?
