yeah. Dora's problems stem from things outside of Marten or his ability to truly control. If anything Dora will simply fall back on the mindset that is common for her mentality type "just like i thought, it didnt work. i knew it wouldnt. it's my fault for getting my hopes up. i always knew something would get in the way, and i was right."
The problem, as stated multiple times above, is that "something" is so general that they themselves are aware of its width, and latch on to the first possible thing. Not so much because they want the relationship to fail, but because it would prove them right. and out of anything, the only thing they believe they have, is their pride. so they take that pride, and work towards making themselves as correct as possible.
"i'm the one in the right. everyone else is wrong. and even if i'm wrong, they were more wrong, more often, and they have no right to hold a grudge." she's of the mindset that wants so badly for that to be true, that she makes it true, by leading herself, and others into bullcrap situations, just so she can justify herself, be correct and reign superior. Hints of this had been shown way back, when Raven first showed up. There was an inflection in Dora's words when she was speaking with Raven, why she left the "coven" and whatnot. she felt herself above such "dumb teenage games" and very vaguely lorded that over the other girl.
Raven, while a goofball, has been proven to have a very sharp brain in there, just either muddled by stupid, or she just doesnt care enough to try to be booksmart, though she could be. she also seems to be a rather non-judgmental person. Unlike Dora who immediately labels people based on a few meetings and actions, and then sticks to that, even if the possibility of change is there. She assumes, she judges, and lord have mercy on whoever does the same with her, even though she's an open book.
Her successes are her own, and she views them as such. she's lonely, but would rather be right and alone, than wrong and with someone. so she'll let people in, but she's constantly watching them the closer they get to her. and she expects herself to always be forgiven because it's her. But if she's not, that person is horrible, and evil and should feel like a waste of space because they dare to bring up something she did wrong. "I apologized, that should be enough for them!" She takes, but she isnt willing to give as much as she takes. She doesnt want to go as far for someone else as they go for her, because she feels she deserves it all for some reason.
Some people might think i'm completely wrong, and maybe i am, but that's how her mentality presents itself. it's not a conscious thing. that is to say it's not so much at the forefront, she's not so much purposefully perpetuating it as it is that it's become a subconscious truth in the back of her mind, and it would take continuous attacks on it before she brings it back to the front, recognizes it for what it truly is, and then works towards banishing it.
Her surface self is perfectly stable. but her surface self is formed from a false foundation, formed from the true self, which is selfish, lonely, but too proud to do what the others do, even if it could work. thus, her subconscious muddles her view of herself. "i have problems, but so does everyone else. I'm just lacking a bit of self-confidence is all! Look at Hannelore! She's INSANE! And Faye! Faye's even more messed up than i am! She's in Therapy for god's sake!" She compares herself subconsciously to the people around her, and generalizes her problems compared to them. Faye has deep mental issues from her father's suicide that she never got over. Hannelore is...well she's Hannelore. Marigold is an otaku. Marten is a doormat. Sven is a man-whore. "Compared to them, i'm perfectly fine! There's nothing wrong with me! I dont need therapy! I've got a successful business, good friends, i'm set!"
And this mentality blinds her to the true problem. She's clinging so hard to what she has, the problem she DOES have, which is a very big one, seems pointless to dwell on. If others leave her, it's their fault. she saw it coming, she was right all along. They're the ones that caused problems. "I apologized. That is enough. that BETTER be enough." At this level, she's got the worse mental problems than Faye or Hannelore. Because theirs are more prominent that they're conscious of them. It's strong enough to mess with their daily lives. They're aware of them. Dora is largely unaware of it until she's cornered and has no choice but to bow, but she wont bow without a massive struggle, even if she was the cause of the problem. the combination of lack of self-confidence being hidden and covered up, pride, and desire to be correct is a fatal one. and it's not at all uncommon in reality, which is probably another reason why i dont like Dora. And just like in reality, nobody wants to be the one to say "look. you're messed up. not like Hannelore or Faye. Worse. Worse because at least they're actively aware of it, they're taking steps. you dont see it. you choose not to see it. you need help because you cant see it. we'll be with you every step of the way."
Honestly, if someone did? Well...now it wouldnt do anything. but maybe down the line it would. But as is, again, i state: Dora is unfit to be with anyone, let alone Marten.
Also i totally would laugh at a Marigold/Marten setup. that would be so hilariously broken it'd be totally worth doing. Wait. Speaking of Raven, where'd she go again? I cant remember.
