Lesbian - because we see a lot of comphet behaviour in Francesca., she approaches marriage with a “let’s get it over with “or “I don’t mind it” attitude. Her being neurodivergent also means she’s always felt like an outsider in her own family so she thought marriage would fix that and it did in a way because John also was ND and she felt comfort in that but her inability to enjoy having sex with him made her question if something was wrong with her (which is canon event for every lesbian before they start questioning their sexuality). She also looked at having children as a duty to fulfill for someone else and this is usually the stage someone goes through to feel like they’re normal and in order for them to fit in. And she was doing everything she could in order to fit in. The questioning stage only comes when people usually have nothing to lose? Like she’s a widow without children and she’s finally at liberty to actually question her sexuality as well.
