There is a mod for the game that one of their discord mods made that you can download and it tells you if the choices end routes, gain affection, or lose affection. https://f95zone.to/threads/evermore-v0-3-prometheus.103770/post-7623880 In my experience to get it to work you need to replace the game folder with the one downloaded in the mod, can't just paste the whole thing into the folder itself.
