Yeh this is what I assumed as well, the first 6 months of them living together did seem a bit dark? Like the coke, living off coffee, they way they dressed etc they just seemed to be dragging each other down. Not to mention it’s been semi confirmed that Flossie slept with spencer while him and Olivia were a thing, tbh if that’s true I’m surprised they’re even still on as good a terms as they are. I feel sorry for Flossie as I think she’s in a rut but maybe being around her is quite draining?maybe a reach but possibly olivia associates her bad few months in London over coke gate with flossie, living with her and the time back when she didn't have all these new friends. especially since her friend lola is celebrating being sober i doubt olivia would feel comfortable to take stuff around her. maybe shes trying to put all that behind her and isolating flossie in the process as she reminds her of that time, could be completely wrong tho
