I think they may be! Remember her rating on her ex? It was based on what she’d said out loud… Maybe they’re based off conversations? But what if the person did you so wrong you’d never say it out loud or something?
Don't think so since her ex's ex never talked about their abuse to anyone. I think it rates people on what the partner thinks of them
I don't think that's the reason either. Not all girlfriends in the story said things out loud. The FL rating to her ex was weird but I thought maybe it will change later? Maybe it's based on the average period of relationships and not how they parted? I'm not sure
Would be a plot twist if the system ratings are misleading
