People that say this type of content is not for you if you go monogamous route with SH or ,,just leave him at camp,, are missing the point, it is about writing, not about having feelings hurt because your fictional girlfriend is attracted to another man. There are a lot of dialogue options that most people would never choose in ironman playthrough, but they choose it out of curiosity to then f8 after. How many people would quick save and then choose the meanest dialogue option just to see npc reaction? And then actually liking (or disliking) character more , based on their response? Or not even liking, but actually learning something important about that character background/personality?
Having an ability to see ,,what if,, scenario is the greatest advantage that video games have when it comes to story telling over any other media type, so having an attitude that everything is fine when some characters do something completely contradicting to their previous behavior just because that dialogue option is not often choosen is kinda silly
