This is fiction, where an author is in control of all the outcomes. If they want it to fall apart in a disaster, then that's the story they'll tell. If they want it to work out anyway, threading the needle despite likely pitfalls, that's the story they'll tell. It doesn't make too much sense to think "this would be unhealthy in real life".That’s terrible advice. I can’t believe the author is still going to proceed with the romance when the story has already shown how unhealthy it is for everyone involved. They all need psychological help, not a relationship.
