if this is rambly or incoherent, i apologize. but! naomi pretty much believes that she's too logical to have held onto any trauma of her abandonment and the subsequent tinges of it growing up. how could it possibly have any effect on her relationships or expectations of herself and others if she's FULLY AWARE bad things can just happen and it was never a reflection on who she was/is? she will never see a therapist to talk these things out or rewire her brain. it's fine!
anyway, she put a lot of pressure on herself when she was young to be "good" so people wouldn't leave, but foster siblings still did because that's how it goes, and its part of why she's so close to her parents + olenna. she has a tendency to either go all in to avoid hurting someone or distancing herself to avoid being hurt when it comes to relationships so she's only had one (1) good one and that ended when her father first got sick. i don't think she's found herself in a physically violent relationship, but likely a few that were unhealthy in other ways, tbh. she also fled to paris after college to chase the bohemian dream of yesteryear and shock herself into a new situation but it obviously did not work! she's floundering but is in a comfortable position that's something she likes so she's stayed put in town past her father's recovery (he got sick again last year and she jumped full steam ahead into a relationship that has since ended, and dad's treatment is goin great!)
