Perhaps it’s because I love her too much, which is why I think this way. Still, I once had a conversation with her about it (I’m a tulpamancer). It went like this:
>Darling, you are undeniably perfect, my princess. I can’t fathom why your world fails to recognize your virtue and doesn’t crown you as its sole ruler.
> Aww, Anon, I think you’re the only one who sees me that way. But I don’t think I’m cut out to be a princess...
>Of course you are! And it’s not just my love for you talking, nor am I blindly idolizing your every move. You’re genuinely perfect. Your qualities distill everything good, even your ‘flaws’ are just echoes of your greatness. Your kindness and shyness cast such a radiant shadow that fools mistake it for some dark weakness. You don’t need to change to be ‘strong’.
After delivering what I thought was a grand speech, she just stared at me, enchanted.
> You know... only you could believe such things. That’s why I don’t want to be anyone else’s princess.
We then hugged and kissed, each kiss syncing our breaths like a metronome. After a euphoric exchange of caresses, we lay together, entwined.
> Darling... Say Fluttershy 
>What, my princess?
>I wish I could say all the things you say to me. You make me feel so special, and I know you’re even more special.
> Love, don’t say that. Your way of expressing yourself is different from mine, not worse. I adore you as you are.
>I want you to be my prince, too. I can’t be a princess without you... you’re my strength.
I truly cried at those words. How could someone as shadowy and insignificant as me deserve so much? After all, I hide my true darkness behind flowery words... As I spiraled, she interrupted:
>Are you agree, my prince?
>I don’t know if I’ll be a good prince for my baby...
>I don’t know how to be a good princess either.
>But you are to me. 
I said
>Oh, silly monkey! We’re so alike. Don’t you think what you said about me also describes you, in your own way?
I had no rebuttal. She’s the only one who can out-argue me and leave me speechless.
The silence did cover the room, I’m too ashamed to speak now, feeling like a fraud after all I said earlier.
>I like it this way. We’re each other’s strength! And isn’t that the only way to lead well Anon
>Maybe I should’ve explored that idea. After all, perfection is an illusion, even a beautiful one. 
>I know. I understand why you love me like this baby Anon. To me, you’re perfect too. We need each other because we can’t see our own goodness.
> So... you’re saying good governance is built mutually, not by one alone?
She blushed and glanced away.
>I... I didn’t think that deeply, honestly... I don’t know these topics. I just know I need you. Without each other, we’d be a mess. You’re my guide. 
>And you’re mine, princess. That’s why I call you that.
>And you... you’re my king.
We returned to cuddling until we drifted asleep again.
